Hi
i have two links one is p2p & other is dsl 512 line.
My core switch is configured as a default route to point to point link.
whenever link goes down i manually route to dsl.
If you have any idea about how to configure my core switch so if my point to point link is down than it will triggured to DSL line & When P2P line is up so traffic can go through P2P.
Please do the needful.
Regards,
Pravin

Hi
There are many ways to achieve that.
But basically, if you have a 5400 core switch you can use the Administrative Distance for that:
Say you first router (p2p) interface is 10.1.1.1
and the dsl router interface (backup internet line) with IP 10.1.1.2
So you add 2 default routes:
SW(config)#ip route 0.0.0.0 0.0.0.0 10.1.1.1
SW(config)#ip route 0.0.0.0 0.0.0.0 10.1.1.2 distance 255
So the first route has a preference, and once it failed, the switch will route to the other one.
More advanced ways can be done like the one that load balance between both with a preference to first one based on (protocol, source IP, Vlan, ....) and that needs a router that has Policy based routing like the ProCurve secure router.
Good Luck !!!
