I'm having some difficulty load balancing two point to point T1's. This is a pretty basic transparent bridge as far as I understand it. I've followed the instructions in example 9 under doc id: 10676 to no avail. The moment I add both t1's to the circuit group I start getting problems reaching hosts on the other side of the bridge. I'll be able to ping them and then two minutes later I can't ping them at all. Then maybe a bit later I can see them again. On one side of the T1's is a 1720 and on the other is a 1721. Both are running 12.3(23). They both get updated with the circuit-group config at the same time. I think I've ruled out the T1's themselves by running the bridge on each T1 separately for some time (at least a week) without problems. But the moment I put them into a circuit group I start getting problems.
This sounds somewhat like a bridge loop maybe? Any tips on verifying this?
Here is the config from the 1720. The 1721 on the other side is basically the same config.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
