i Diptish,
I believe you could peer with both MPLS Service Providers
ans provide connectivity between multiple VPNS in each. I
think that vrf-lite on the CE will provide the
functionaity you are looking for. To implement this you
would be looking at a separate eBGP peer with the PE for
each VPN for each Service Provider. eg. If Service
Provider A you had VPNs 1, 2 and 3 then you'd use 3 eBGP
peers (3 sub-interfaces on one physical link) to that PE
and likewise to Service Provider B's PE for VPNs 1, 2 and
3. On the CE you could place the same VPN subinterfaces in
the same VRF. Just a thought.
Cheers,
John
