    Hi, It depends what kind of the bridges we are talking about, but yes, full duplex mode is there
  6. Hi, Which application is better ? I am using Putty (becouse of tabs, macro login etc) but i have seen SecureCRT + scripts and it was impressive. For example: after every login to device config has been downloaded (text file), automatic login to configured session etc etc. Do you know some scripts for putty ? How to upgrade it ? (i found extra_putty - but this is not what i have expected). Please share your experiences

    Authentication + ACL = confusion

    Hi, I am a little bit confused and need some clarification/help. There is diagram: Some servers (outside location) ----------------- router (two interfaces / two accesslist : 1- admin, 2 production) servers are in admin - production - and what i need: 1 - connection from servers without authentication - reach production site / the rest traffic/ppl have to be authenticated 2 - communication between production and admin (and in other way as well) without any authentication etc ip auth proxy is assigned to the admin interface if configuration look like below: Admin ACL: permit ip --- server -> production site permit ip ------ admin -> production Production ACL: permit ip ---- production -> admin ip auth proxy ACL: deny ip deny ip ------- without authentication servers admin + production site. permit ip any any The problem is that this solution is working ~80% I have some problems from admin site to reach servers in production on 50000 port .... but on port 80 is working fine Any idea ? Some tips or advice ? I read - > Link

    what is multilink

    Overal and in shortcut - multilink is virtual interface, provides a method for spreading traffic across multiple physical WAN links (load balancing etc). Could be ppp over multilink frame-relay. Configuration guide you can find on cisco website -> Here FRAME

    741 input errors,738 crc

    check settings on the interfaces (duplex mode, and speed - try to set manually 10 or 100 Mbits/s on both interfaces), check cabling, clear counters and monitor it.

    OSPF P2P + subinterfaces

    Hi, I created very easy lab for GNS-3. OSPF Point-to-Point using subinterfaces. I made some small howto configure it. I need your opinion about that. If it is not waste of the time, next will be easy lab for ISCW (tunneling +EIGRP). Both files (howto and gns.net file) you can find here: hxxp://www.[nofileshares].com/file/111735021/81095737/OSPF_P2P_with_subinterfaces.html hxxp://www.[nofileshares].com/file/111735020/f60e67a1/OSPF_subinterfaces.html [nofileshares] = 4 shared . com

    opening ports in cisco routers

    You need to open UDP ports 500 and 4500 (of the VPN gateway). The first packets are exchanged on port 500, then NAT-T negotiation moves the transaction to port 4500.
  15. When you have OSPF (for example and EIGRP (for example on router R3 you have to configure redistribution (please take a look below), configuration on R3, for example: router eigrp 1 network no auto-summary redistribute ospf 100 router ospf 100 network area 0 redistribute eigrp 1 subnets on R1 configure only EIGRP, on R2 OSPF. please read more about redistribution, how to redistribute routing protocols etc. I hope i help u.
