I have installed an IOS image that supports MPLS on my 3 2610XM routers. I have them connected to a 2520 FR switch via serial
R2 - R1 - R3
OSPF is running between them advertising lo0 which is 188.8.131.52, 184.108.40.206 and 220.127.116.11
I believe that I have configured MPLS and LDP correctly,
show mpls ldp neighbor shows all 3 routers talking.
My Question is this, why does the "BYTES TAG SWITCHED" show as "0" on all 3 routers ?
Here is the output of show mpls on R1
Local Outgoing Prefix Bytes tag Outgoing Next Hop
tag tag or VC or Tunnel Id switched interface
16 Untagged 18.104.22.168/32 0 Se0/0 22.214.171.124
17 Pop tag 126.96.36.199/32 0 Se0/0 188.8.131.52
I had to add a line on R1 to get LDP working to R3 as follows,
mpls ldp neighbor 184.108.40.206 targeted ldp
I am very new to this and just want to understand the basic concepts in a small lab environment so forgive me if this one is obvious !!
use point-to-point subinterfaces. There might be NBMA issues.
In my test labs I always used p2p subinterfaces and it always worked well.
