VRF-Lite

[olly ahmed]

Why we use  the command "capability vrf-lite" ?

Hi,

it's useful when you have OSPF as CE-PE routing protocol. In this scenario if CE has vrf configured, the advertisement from PE are rejected because of DN bit (an MPLS anti-loop technology). If you use vrf capabilities advertisement are not rejected.

PS: rate if useful

Hi,

it is also needed in "true" VRF-Lite (without BGP/MPLS)  environments with non-backbone internal routers:
