Hello all.
I'm hoping someone will offer a hand. I'm trying to achieve failover in a slightly strange scenario without using a full routing table.
I use a Catalyst 3550 and because it's limited I just take a default route off an ISP via two BGP neighbours. I use "ip route 0.0.0.0
0.0.0.0 172.1.1.1" to push all outgoing traffic to them using their private LAN IP.I want to add another bandwidth provider but all I will be given is another private IP 172.1.1.2 to send traffic to. I can easily write a script to ping the primary IP periodically and change the default route if it fails to respond for outgoing traffic.
My question is how do I affect incoming traffic if the primary provider has problems but is still visible to my pings ?
The two bandwidth providers will be visible from the same BGP neighbours so I can't drop the sessions and stop advertising them or pad out with prepends. I also only connect to one physical port.
Any help greatly appreciated ! I'm stumped.
