As far as I know, forwarding multicast packet with basic MPLS label is not supported yet. So in a MPLS enabled SP core, multicast is still being forwarded exact the same way as in pure IPv4 network. So you don't need to do extra in MPLS core.There is...

Because when vrf-lite is configured in 3550, the 3550 interfaces connecting to 2900 will be configured as VRF interfaces, so EIGRP cannot be used in these vrf interfaces. you can only run EIGRP in the customer networks on and behind 2900, you need to...

Yes, you are right, the PE-CE link should be configured as layer 3. Typical VRF-lite design uses VLAN sub-interfaces in the CE-PE link, so each VRF can use one sub-interface (in 3550 case, each vrf uses one vlan interface). So the CE-PE link is reall...

RAJ, Sorry, what hyperlink are you looking for? If you are looking for 3550 VRF lite configuration information, here you are: http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12120ea2/3550scg/3550scg.pdfThanks,Cary

Now I understand what you are really looking for, and it makes much more sense. Based on your information, changing the core (Cat6500 GE ring via SONET) from layer 2 to layer 3 will definitely optimize the bandwidth utilization in the SONET ring. Sep...
