VRFs - "ip verify unicast reverse-path"

[jbhatia_9]

Is anybody aware as to wether the command "ip verify unicast reverse-path" works for interfaces in VRF's.

And if yes, do I need to tweak the command in anyway.

Thanks,

J. Bhatia

Unicast RPF is indeed supported on a VRF interface. No special configuration is required.

Let me know if I answered your question,

Hi Hritter,

Sorry to interrupt this message, what is Unicast RPF? When or under what circumstances or suggested that we used Unicast RPF?

thanks :)

Unicast RPF (or uRPF) stands for unicast reverse path forwarding and is a security feature design to prevent IP spoofing.

It validates that the source IP address of packets received on a given interface is resolvable via that same interface.

For more information on uRPF, please see the following URL:
