influencing path based on source address

[farooq_0923@hotmail.com]

Hi Guys,

Need an expert advise on scenario, i have core switch which has default route configured, For few specific ip i dont want it to take default route i want it to take static route path pointing to route than default. i know core switch would do route lookup when it looks at destination address and choose defualt or wt eva configured but how can i make core switch to ignore default if source is lets say 10.1.1.1 and dest any, for rest of network use default gateway.....thanks

regards

Hi,

You'll need Policy Based Routing to accomplish this:

There is a feature of Policy Based Routing which can make routing decisions based on source address. It sounds like this is what you would need if I am understanding correctly what your requirements are. PBR is supported on some switches and I would hope that your core switch would be one that does support this feature.

Hello Mohammad,

See here:

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/layer3.html#wpmkr1033564

The Policy Feature Card (PFC) and any Distributed  Feature Cards (DFCs) provide hardware support for policy-based routing  (PBR) for route-map sequences that use the

match ip address

set ip next-hop

ip default next-hop

I am not aware of any alternative other than PBR that will route traffic based on source address.
