Redundant VPN with IBGP - Newbie Question

Discussion in 'Cisco' started by Charles Jennings, Jun 3, 2004.

  1. I need some help/direction on setting up redundancy in the following
    situation:

    Site A:
    **********************************************************************
    * ISP A (E1)-----PIX Firewall----3725 Router----Interior LAN *
    * | *
    * | *
    * ISP B (Cable Modem)----------------| *
    **********************************************************************

    Site B:
    **********************************************************************
    * ISP A (T1)-----PIX Firewall----3725 Router----Interior LAN *
    * | *
    * | *
    * ISP B (T1)------------------VPN Concentrator *
    **********************************************************************

    I have a tunnel setup between the two PIX firewalls which is my
    preferred route
    I have a tunnel setup between the 3725 (Site A) and the VPN
    Concentrator (Site B).

    Currently, I have to manually change the default routes on the two
    3725 routers in a recovery situation of a preferred route failure.

    I have tried to read up on BGP - but don't quite understand how to
    configure in this situation to automatically fail over to the second
    tunnel in case of a failure in the primary tunnel.

    Can someone out there with BGP experience help me to configure this
    fail-over. I would greatly appreciate configuration example on each 3725.

    Thanks,

    Charles Jennings
