is there a way to enable pbr on vrf interface?

hi all,

currently, i have a requirement to enable pbr in vrf interface of a 4948 switch. but as i browse the internet, it is quite impossible to do that. is there any alternative way / feature to get the same result as pbr does? which is to reroute the specific vrf traffic to another interface based on source and destination ip address?

thanks in advance.

Hello Kawak,

your issue is platform dependent, that is specific of these type of multilayer switch.

A software based router like an ISR or ISR2 ( C2800 or similar) might be able to perform this action.

configuration guide is clear about the limitation it is not a question of IOS version

"PBR  configuration is only allowed on interfaces belonging to the global  routing table. PBR is not supported on interfaces that belong to VRFs"

So only adding a separate box could be a fix.

there is a feature called source based VRF selection but it should be supported only on provider class nodes like C12000 or above.

Hope to help
