To directly answer your question. No MP-BGP is not used only for MPLS. Keep in mind that MP-BGP includes ipv4, ipv6, multicast for each, and vpnv4. However the address family vpnv4 is used for transporting VRF routing information between PE routers.
When you run MPLS L3 VPN the following should be configured 1.) IGP setup and functional between service provider routers 2.) ip cef globally on all service provider routers 3.) mpls ip enabled on all interfaces between service provider routers 4.) VRF instances configured on Provider Edge routers 5.) Configure route-target import and export on PE Edge routers under the VRF instance 6.) MP-BGP peering with the vpnv4 address family between provider edge routers 7.) Interfaces facing the "clients" should have "ip vrf forwarding" configured for the approprate VRF 8.) Routing should be configured towards the client. 9.) Finally, necessary redistribution between PE-CE routing protocol and MP-BGP under the ipv4 vrf VFRX address family Those are the basics of MPLS L3 VPN that you need Aaron On Mon, Jun 27, 2011 at 9:14 AM, Poonam <[email protected]> wrote: > Question; > > Do you always setup vpnv4 address family when configuring MP-bgp, no matter > the protocol running over it ? and is MP-bgp explicitly linked to MPLS ? > it all seems to mesh with one another, i.e. we almost always seem to use > mpls vpn's in conjunction with mp-bgp. > > in the previous labs i was doing it seemed as the vpnv4 'carried' the VRF > information. > > rgds, > Alef > > _______________________________________________ > For more information regarding industry leading CCIE Lab training, please > visit www.ipexpert.com > > Are you a CCNP or CCIE and looking for a job?
