  1. I have a voice lab that is set up like so: CME------GW------PSTN | | | | | | 2001 3001 411 CME and GW are connected via ethernet, GW and PSTN are connected via 2 back to back vwic mft cards. Im using CME 8 on everything. Everything seems to work ok, but i can call 411 from 2001, I can dial 411 from 3001, and i can even dial 2001 from 411....I'm not sure what the problem is but I think it's something on the dial peers or the voice port configs, here is what I got CME --- dial-peer voice 50 voip destination-pattern 300. session target ipv4: ! dial-peer voice 411 voip destination-pattern 9... session target ipv4: GW -- interface Serial0/2/0:23 no ip address encapsulation hdlc isdn switch-type primary-ni isdn incoming-voice voice no cdp enable ! dial-peer voice 1 voip destination-pattern 2... session target ipv4: ! dial-peer voice 411 pots destination-pattern 9... port 0/2/0:23 forward-digits 0 PSTN ---- interface Serial0/1/0:23 no ip address encapsulation hdlc isdn switch-type primary-ni isdn protocol-emulate network isdn incoming-voice voice no cdp enable dial-peer voice 2000 pots destination-pattern 2... no digit-strip port 0/1/0:23 ! dial-peer voice 3000 pots destination-pattern 3... no digit-strip port 0/1/0:23 I can certainly post more of the config if needed, another thing that's bugging me is that when I dial 3001 or 2001 from 411 i get a dial tone and I need to dial it again to actually make the phone ring, I was doing a bit of research and it looks like PLAR will fix that but it seems to only work for one line. Any help would be appreciated.

    spanning-tree root command

    Oops here try this link http://www.cisco.com/en/US/docs/ios/lanswitch/command/reference/lsw_s2.html#wp1113230

    spanning-tree root command

    Ok this is bugging me http://www.cisco.com/en/US/docs/ios/lanswitch/command/reference/lsw_s2.html#wp1113230 The spanning-tree root primary command alters this switch's bridge priority to 8192. If you enter the spanning-tree root primary command and the switch does not become the root switch, then the bridge priority is changed to 100 less than the bridge priority of the current bridge. If the switch still does not become the root, an error results. The spanning-tree root secondary command alters this switch's bridge priority to 16384. If the root switch should fail, this switch becomes the next root switch. 8192.....16384.......Whats the deal? Im trying to tell my boss that is 24576 and 28672, then he sent me that.... Can someone explain this to me, is this page wrong?

    IPv6 address confusion

    Ahhhhh ok yes this makes perfect since, I changed R2's ip add to a::a/126 and sure enough it didn’t work......thanks for the explanation.

    IPv6 address confusion

    I have 2 routers connected running IPv6 R1 is using the address a::f/126 and R2 is using the address a::e/126 My question is how can these addresses be legit? When I’m looking at a /126 prefix length that only leaves 2 bits for the hosts.....right? So I would think that a::1 through a::3 would be the only usable host addresses, but that’s not true it seems to not only let me configure all the way up to a::F but it works! I don’t understand how this is possible?

    iBGP nex-hop-self and a route-map

    For the life of me I cant figure out to inset pics into my post so i just got links.....sry for making you jump around to different web links Here is my topology http://www.freeimagehosting.net/wgj53 R1 and R2 - iBGP R2 and R3 - eBGP R2 and R4 - eBGP R3 and R4 - iBGP I got a route-map on R1 as follows route-map 3434NET, permit, sequence 10 Match clauses: ip address (access-lists): 10 Set clauses: local-preference 200 Policy routing matches: 0 packets, 0 bytes route-map 3434NET, permit, sequence 20 Match clauses: Set clauses: local-preference 100 And here is ACL 10 permit, wildcard bits I have applied the route-map like so under the bgp config on R1 neighbor route-map 3434NET in When I look at the bgp table in R1 I see this. http://www.freeimagehosting.net/8lplh This all makes since to me and is what I expected to see. If I go to R1 and issue "neigh next-hop-self" and do "sh ip bgp" this is what I get http://www.freeimagehosting.net/nihpa R2 is no longer advertising the network I only see it being advertised by R3, If I remove "neighbor route-map 3434NET in" from my bgp config I can see R2 advertising the route again. This is really confusing to me as I wouldn’t think a route map applied to the R3 neighbor would affect a route being advertized by R2. Furthermore if I remove the next-hop-self command from R1 and leave the "neighbor route-map 3434NET in" on R1 I see R2 advertizing the route, I don’t understand why setting the next-hop-self on R1 would cause R2 to stop advertizing this route.

    Content Enging Netowork Module

    I have a content enging NM in a 2600 and was using it for a tftp server, also to just kinda play with....I seem to have it all set up and configured. I can copy stuff to and from the tftp. The problem im having is I cannot figure out how to display the contents of the tftp server from the 2600 2600#dir ? /all List all files /recursive List files recursively all-filesystems List files on all filesystems archive: Directory or file name cns: Directory or file name flash: Directory or file name null: Directory or file name nvram: Directory or file name system: Directory or file name tar: Directory or file name tmpsys: Directory or file name xmodem: Directory or file name ymodem: Directory or file name <cr> 2600#dir How....if its even possible do I get tftp: added to this list? Or is there some other way to display it without actually opening a session to the content engine?

    Eigrp Metric

    Is there ever really a reason to change the K values or the bandwidth and delay of the interface, as far as eigrp metric is concerned? It seems like an offset list is really the best way to manipulate the metric. Cisco book says: "In practice the most reasonable and commonly used methods are to set the interface delay and bandwidth" But then they say it’s not such a good idea to set the BW as it affects other things, especially WAN links as the BW is usually set in relation to the CIR and all that. They also mention that changing the delay can affect other thing, but they don’t mention what that is.... Why would anyone want to bother with that horrid K value calculation changing those looks like the most complicated way to manipulate the metric, why even do it at all? So it really seems like an offset list would be the simplest/cleanest way. The only thing I can think is that using an offset list would cause some extra CPU usage, and that’s why Cisco doesn’t say it’s the most reasonable and commonly used method to change the metrics.

    Hey Hey I got a CCNA

    I passed the ICND2 giving me my CCNA....WOOOOT!! I wanted to share a few things about the test First off time was a big deal for me, with the ICND1 I finished with something lik 25 min left on the clock, but with the ICND2 I only had 30 sec left, and ended up just guessing on the last 2 questions because I was afraid I was going to run out of time. The test was a total of 43 questions and I passed with 860, I was so friggin nervous durring the test its amazing I was able to think at all....I actually answered a few questions incorrecctly and realized it just as I was hitting the next button....simple questions like whats the AD of a protocol, so id like to say take it slow and make sure of your answer, but damn with only 30 sec left on the clock....it was rough for me, I was sweating bullets. Second this test was alot harder than I was expecting, the questions were confusing and nothing like they are in the book or the study exams I got from train signals. My first question was a router simulation that I spent 15m on.....uuugggghh....I spent most of the time reading and re-reading the questions just to make sure I understood what they were asking because they were that confusing to me. Lastly cisco had a pretty scarry disclamer about not sharing test questions and all that, but ill say there was alot more IPv6 than I was expecting....I think I had something like 5 or 6 questions just on ipv6, and ill admit I was not as ready for them as I would like to have been. I wanted to share with yall because these boards are awsome and I get so much info out of them, hopefully this will help someone. So I think its off to the CCNP Route book next....

    Static routes from my ISP

    I have a cisco 806 that plugs into a comcast cable modem via the e1 interface interface Ethernet1 ip address dhcp client-id Ethernet1 ip nat outside no cdp enable Here is the output from sh ip route 806#sh ip route Gateway of last resort is to network is subnetted, 1 subnets S [254/0] via, Ethernet1 is subnetted, 1 subnets C is directly connected, Ethernet1 is subnetted, 1 subnets C is directly connected, Ethernet0 S* [254/0] via 806# My question is why are they giving me a static route to if they are already giving me a default static route that points to the same IP? They even have the same AD Seems pointless to me....if I have traffic that is destined to the address wouldn’t the default route take care of that? Also I’m not really sure what that address even is...my DNS servers are on the 68.87.x.x network but not that IP, so im thinking it has something to do with DNS but I still dont understand why its even there is the 1st place.

    Static Routes

    AHHHHHH friggin NAT, how could I overlook that!! Also the static route back to the 2514, I wouldnt have thought of that.....Awsome!!!

    Static Routes

    Here is my topology ISP-----806-----2621-----2514 I have a ISP that plugs into a Cisco 806 that connects to a 2621 that connects to a 2514 So the 806 can get out to the internet no problems. on the 2621 i enter the command ip route fa0/0 This works, all traffic that the router doesn’t have an entry for in the routing table it sends out fa0/0 to the 806, and the 806 in turn sends it to the internet. So then I went to the 2514 and entered the command ip route e0 But the 2514 can’t get out to the internet. My thinking on this is......all traffic the 2514 gets that it does not have a destination for it will send out e0 to the 2621(right?)......and in turn if the 2621 does not have a route it will just send it out fa0/0 to the 806(right?), but that does not seem to be happening....if I attempt to ping something like from the 2514 it dies at the 2621. I can ping the interface of the 2621 ( that connects to the 806 but I cannot ping the interface of the 806 ( on that link. What am I missing here? How come the static route on the 2621 is not forwarding the traffic from the 2514? Any help suggestions are greatly appreciated.

    2600xm Routers

    I’m am looking to buy a 2600xm router, I was researching their series and looking at the differences between Cisco 2620xm vs. 2650xm And 2621xm vs. 2651xm From what I can tell they have the same interfaces, support the same max flash/DRAM/bootROM. I am not able to find any difference between these routers. Is there any reason to buy a 2650xm over a 2620xm or a 2651xm over a 2621xm?

    Telnet to home lab

    Yup thats it!! Thanks a ton this is going to help so much. BTW, any idea why I was not able to forward the tenlet port with the command that I used? I used the other command suggested but then I wasnt able to telnet at all!!
