VRF forward / receive, which one is best?

[gordonderick]

Can anyone tell me  the difference between 'ip vrf receive' and 'ip vrf forwarding', do these 2 commands put the interfaces in the VRF?

I have a interface on the core configured with 'ip vrf recieve' (config below). Wheneve the edge device is disconnected from the network the 'ip vrf receive' command disappears from the running config.

Hi Gordon,

"ip vrf receive" is used in the context of multi-vrf selection, which allows to have multiple VRF assigned to an interface and to select one the other basec on the source address (or other information using PBR).

"ip vrf forwarding" enables one VRF on a given interface.

Hope this helps
