2.2 SW2 connectivity to external routes

Since SW2 is only running EIGRP and not BGP how is everyone getting full connectivity for SW2.  I can hit everything internal, but no joy when trying to reach the external routes.  I did not see anything in the solutions guide about setting up BGP peering or doing any type of redisribution from R2.

    Since SW2 is only running EIGRP and not BGP how is everyone getting full connectivity for SW2.  I can hit everything internal, but no joy when trying to reach the external routes.  I did not see anything in the solutions guide about setting up BGP peering or doing any type of redisribution from R2.

    Hi Lancen,

    This task does not involve BGP yet.

    In general, redistribution is working, because you can reach the other IGP domains.

    Try this....

    1. Make sure those routes are being advertised into the internal domain.

    2. a. If the routes do exist, then do a traceroute.  Is there a loop?

       b. read the "Strategy Tip".  Are the "connected" interfaces being advertised?

     

     

  • Right SW2 does not have a BGP connection.  The problem is he does not see these routes at all, and I am wondering how would SW2 get these routes if say for example R2 learns these routes via BGP.

  • Right SW2 is only running in EIGRP 100 domain, no BGP so he does not have those routes even installed in the routing table.  So how does he get those external routes when they are learned via BGP for R2 and the others in that same domain.

  • Right SW2 is not running BGP it is running only in EIGRP 100 domain. It does not have a route to those external networks so no loops, and not sure how they would get the routes since R2 and the others in that domain are learning them via BGP. Did anyone else run into this, I cannot imagine the TCL ping script would have worked for them without some type of modification to allow those routes to SW2.

    You found the issue.    eBGP (20) has a lower AD (on sw4).   It is a problem with the lab setup.

     

    Try this. Marknotrust posted this in another thread:

    Rack8SW4(config)#router bgp 200


    Rack8SW4(config-router)# neighbor 192.10.x.254 shutdown

    Hi Lancen,

    I am not sure what happen with your multiple posts above.  Hopefully my last post helped you solve this.

    The answer is to shutdown the bgp neighbor on SW4.   The other option is to filter those routes, but this option is sufficient to test it.  These labs are still for learning.  They do not count as mock labs.   I think this is a lab setup problem, so just learn the lesson and move on.

  • Aww I see, thanks Joe.  Not sure what happened for some reason when I replied it did not show up and I got a message saying it needed to be approved my a moderator lol I actually went in and changed the distance for the rip process down to 19 and that also seamed to work so far.  Thanks for your help :)

  • JoeMJoeM ✭✭✭

    ha   That is even better. More permanent.  ;-)
