Backup routing using Cisco 3550
Posted on 2004-10-06
I have a Cisco 3550 EMI switch which is the default gateway of my all hosts in my LAN. I have a point-to-point link to a client site which terminates on a Cisco 2610 router and the router is connected to the 3550. I have a Cisco PIX firewall from where I have a VPN to the same client site. The trusted interface of the PIX terminates on the 3550 as well.
Now I want that when the point-to-point link goes down ... all traffic should automatically be routed through the VPN. Please let me know the configuration that should be done in the switch to achieve this.
