I have seen some example of option B (ASBRs exchanging VPNv4 routes) and send-label being used...however I have it working without it. I doubt it is needed because the ASBR's share their own local label for VPN routes with each other and this put in their LFIB. The FEC is actually a VPNv4 route.
Topology: R1-R2 are AS100 R6,R7 are AS200 R3 is in VRF R1 ---- R5 ---- | ---- R6 ---- R7 ---- vrf ---- R3 >From R6: Local Outgoing Prefix 604 703 200:1:3.3.3.3/32 >From R5: Local Outgoing Prefix 505 604 200:1:3.3.3.3/32 No routers have send-label and everything works fine. Is there a reason I see send-label used with option B? -- Bryan Bartik CCIE #23707 (R&S), CCNP Sr. Support Engineer - IPexpert, Inc. URL: http://www.IPexpert.com
