no capability vrf-lite
Hi People.
I am trying to understand vrf capabilities under ospf, please use the following link as the example for my question http://tinyurl.com/create.php
I understand the creation of the tunnels towards each PE using the ssm address as the destination address in the MDT Tunnel, and that the source would be the configuration that we do under the VPNv4 BGP Address family for this auto magical multcast tunnel
My question is more related to the Routing Context, not to Multicast (for now 
) what would happen if I configure no capabilities vrf-lite under each CE? assuming that the routers are configured with ospf instead of RIP as the routing context
is this no capability vrf-lite configuration necessary if ospf was used as the routing context between the CE/PEs in the CE Router for that figure?
I understand that the PE would would ignore the routes that have the Down Bit set, and this would originate that the route is not redistributed into MPBGP,, and that this OSPF DB gets marked when they cross from their area, converting them as Lsa type 3 in other PE, and with that mark other PE connected to the same site would ignore the route an solve the possible loops that can be created.. (so this is the basics)
but I am stuck with that capability vr-lite under the ospf that runs between the PE and the CEs, when do we need to configure this?
Can someone please elaborate more about this?
Thanks for any comments
