Hi David,
Thanks for your input.
The ISP in this case is providing a 1GB Ethernet to the data centre CE from
their PE.
They will be providing one Dot1q interface per VPN. CE to PE connection is
running EBGP.
If the ISP who is handling the PE is just announcing the prefixes to the
CE router, the CE router at the DC will be receiving all the routes of the
sites
through dot1q and will be seen in a single routing table.
In this scenario, can the customer who does not manage the PE router,
configure VRF-lite on the CE without the PE router sending the routes
which are VRF aware.
I am new to MPLS. I am still on the learning curve. If you can clarify this
problem
for me. BTW, the ISP is using Alcatel in their MPLS cloud.
Regards
Shameen
