How to setup redundant circuits in a 4507 core

planzone · ‎01-23-2008

Hi,

was curious what a config would look like if I were to setup my core switch to have a redundant wan circuit. Example I have (2) managed AT&T routers that are connected to our MPLS. If for some reason the circuits are out how can I have it roll over to my DSL circuit as an emergency backup ? To have connectivity? What would the config look like for something like that?

You would put a static route in the cores with a higher administrative distance than your IGP (pointing to DSL). For example-

ip route 192.168.5.0 0.0.0.255 10.10.10.50 220

HTH and please rate.

you can also setup another default route

0.0.0.0 0.0.0.0

If you have a PIX, you could build an IPSec VPN tunnel to have a redundant connection.
