ip vrf forwarding, crap my net is down !

[ddvoyer]

Hello,

Why when I put the command "ip vrf forwarding blabla" on an interface (ex: int fa0/1), it remove my ip address ? :(

This is normal behavior. The address will be removed from the interface when you apply or remove "ip vrf forwarding" so that the address is not automatically moved from the global to the vrf and vice versa.

Hope this helps,

Dan,

That is expected behavior. When you associate an interface to a VRF, all IP information is removed from the interface. This is because the interface is now removed from being associated with the global table and now associated with the vrf you defined. It essentially appears as a new interface to that vrf and therefore all previous IP information is removed.

Hope this helps.

now I understand, thank you.
