Helo, Hub and spoke frame-relay with R1 as hub. R2 and R3 are PE-routers to R4 and R5.

R1 does not advertise labels for these networks to the other spoke. For example, this is how R2 sees R3's loopback: R2#show mpls forwarding-table 200.3.3.3 Local Outgoing Prefix Bytes Label Outgoing Next Hop Label Label or VC or Tunnel Id Switched interface 16 No Label 200.3.3.3/32 0 Se1/0.123 point2point With a direct link between R2 and R3 labels for the V1 vrf connecting R4 and R5 are distributed and everything works just fine. If i disable R2's link in the FR cloud and instead enable a direct back-to-back serial between R1 and R2 (with the direct link between R2 and R3 disabled so that traffic goes R2-back-to-back->R1-FR-cloud->R3) everything works as well. What am I missing? Is this expected behavior in a FR hub-and-spoke scenario? thanks, Magnus _______________________________________________ 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?
