MPLS TE over Port-channel interfaces


I get the following 'warning' when configuring MPLS TE on a port-channel interface. Any comments on what the limitations to using TE on a port-channel interface are?

7606(config)#interface port-channel99

7606(config-if)#mpls traffic-eng tunnels

%Warning: MPLS TE support is limited for port-channel interfaces.

For additional information, please contact the MPLS TE product manager.

I think that you might be hitting the bug CSCsi55462.Traffic Engineering is not a supported configuration under

port-channel interface. However, limited support for Traffic

Engineering is allowed with the following caveats:

1) Zero bandwidth tunnel

2) No FRR support


I configured TE and FRR on Port-Channel also. I saw some TE Tunnels worked with FRR, some didn't. I enclose here for reference.

Can you explain more detail about the limited support for TE on Port-channel?

Many thanks

Hi all,

I make some configuration mistake. It'w fixed and now all TE tunnel work with FRR.

By the way, can anyone explain more about the limited support for TE on port-channel?

Thanks anyway,

Hi, we have a similar problem. We aer trying configure MPLS TE under poertchannel interface, and it's not is not recognized. We have two chassis 6509 in VSS.

So, we need help.
