MPLS CBTS TE - Tunnel not routing EXP properly

dan · ‎07-23-2010

Hello,

We are working on TE within our MPLS environment and want to employ CBTS. I have configured this according to the "MPLS Traffic Engineering: Class-based Tunnel Selection" doc. The tunnels are up but do not seem to be recognizing the configured EXP values. I have setup TEST polic-maps so I can verify the packets have the proper EXP set in the label but the tunnels just seem to be totally disregarding it. I have attached the config for review. Any assistance would be greatly appreciated.

Notes:

These are P to P tunnels. We are using 7206VXRs with the c7200-adventerprisek9-mz.124-24.T3.bin image.

Thanks in advance!

Dan

Hello Daniel,

>> These are P to P tunnels. We are using 7206VXRs with the c7200-adventerprisek9-mz.124-24.T3.bin image.

my guess is that the trouble is in the first sentence (unless it is a typing error), PE nodes are the ones that can choice what LSP to use for sending traffic.

P nodes are internal to the MPLS cloud.

you are referring to this link:
