Port-channel algorithm on 7200 or GSR

Unanswered Question
Feb 9th, 2010


Please help me to find out which is the algorithm used by 7200 or GSR on (GE) port-channel configuration!

GSR would be the P router, 7200 is the PE.


CE --- PE (7600) === P (GSR) === PE (7200) --- CE

7600 works well, but GSR and 7200 using only one link of two. This is an MPLS^VPN environment.

I used same source and different dst IP addresses during test.

Thank you for your help!

Hello Gabor,

C7200 and GSR are routers not multilayer switches I would suggest you to remove port-channel configuration and to use the two links as two parallel L3 links.

Hope to help
