  1. Ok, my reply is not going to spoon feed you. It will give you only ideas and some questions. Since you "read some T1 configuration but got confused", I think thie method could help you. - Who is going to provide the clocking? - The T1 Controller needs to be configured under ‚Controller t1’. Find out which options to configure. (eg. Which switch type do you need to use?) - Are any new ports available on Router after the controller config? - How many channels has the T1? How many of them can you use? - Do you need to configure any new ports available after previous config? How? All the best.

    MPLS LAB issue

    I suspect that Lord Flasheart's post has been removed from which the original poster is quoting. And I also suspect that it might be Darby who did this. Please either correct me or restore the post. Tnanks.

    You say you have 4 computers and one printer in your VLAN1. Please let us understand how they are connected to the router. Looking at the router config, I see two ethernet ports shutdown and two in default configuration, without any VLAN assigned to them.

    I simulated this using a cable modem connection. I have a Cable Modem connection with provider's cable modem at my place. I connected my lab 2821 router behind the cable modem. Had to struggle a bit, as the 2821 was a bit too heavily configured. Had to remove the E1 card and the FXO card to get the configuration to work. Outside and inside interfaces are both gigabit ethernet interfaces. The configuration was easier than yours. No VLANs were required. Configured NAT. Connected my PC to the inside interface. Connected the outside interface to the cable modem. The outside interface of the 2821 got the IP address from its DHCP Server nicely. DHCP Server was configured on the 2821 so that my PC (home network) could get an IP address. My PC got IP address fine. Switched off the PC's Windows firewall. (PC runs Windows XP). All went well. I can now surf Internet using the 2821 from my PC. I did not have to configure the default route (initially I configured, but it did not work. Then I removed it and found out that the default route was already provided by the cable modem. I could ping my PC from the router fine. SO, I would not know really what the issue is. One of the major differences in your config and mine is that you are using VLAN and I am not. The other difference of using ATM should not really matter. Sorry, cannot help you further.

    By looking at your DHCP config, there cannot be more than 6 hosts in VLAN1. Out of that, you have denied one host in the ACL. From where are you trying to ping which host?

    Ok. After a second thought, I am wondering how the configuration is working even when there is no encapsulation configured under the PVC. (I mean encapsulation aal5mux etc.) Any comments from experts here? Thanks.

    And if it is not the Windows Firewall, could you try the configuration without the deny statements in your access lists? Also, I have never seen the "ip virtual-reassembly" command. Could anyone point out what is this statement for? Thanks.

    Need Help For Load Balancing Between Two Diff. Isps

    Was going through a few old posts here and labbing some of them. Also found this one and labbed it. What is missing these days is the sarcastic sense of humour of people like Lord Flasheart from the posts.

    An ABR never sends LSA type 4. The type 4 LSA is the IP address of the ASBR. THe ABR uses LSA type 3.

    preparing for CCIE SP LAB in march

    Hello, I am not an expert and here are my 2 cents: I came across this issue on another vendors lab. Routes available and could not be pinged. The vendor offered the explanation that this was because the intermediatory routes were not advertised into the protocol and so it was expected that a host within that prefix could not be pinged even if its route was available. Could any of you experts out there confirm this?

    HI Sandeep, Thanks a lot for the info. I am sending you a PM.

    Hello experts, Could you please point me which resources I could use to prepare for and understand ATM technology as it relates to SP lab and written? I read some configuration examples and some theory, but the basics remain missing. Thanks.

    MBGP and MP BGP

    Hi guys, I am now preparing for MPLS. One doubt which I have is: what is the difference between MBGP and MPBGP? Are they the same? Thanks for clarifying my doubt.
  14. Even my goal is CCIE SP. I cleared my CCNA in August 2008. Then I did BSCI/BCMSN Composite. Now I want to go in for 3 CCIP papers; namely BGP, QoS and MPLS. BGP preparations are complete. But I am finding MPLS tough and even QoS seems tricky. These 3 subjects are important for CCIE SP. I would also like suggestions from experts as to how to go about preparation. Thanks.

    MPLS mtu

    Not sure what your doubt is and I am not an expert. But here are my 2 cents: Each MPLS label is 4 bytes. There are maximum 3 labels in a frame making it 1500+12 = 1512 bytes max. So, the switch should be configured to support 1512 bytes frames.
