Hi John,
...that will not work - you will have to change the network type to pt-to-pt on all four interfaces.
I have just started catching up on this thread ...I am curious:
The new port-channels on r1 and r2 are the interface-stats for channel-group members clean? are they all full-dup on both ends? same method for bundling links on r1 and r2 correct?
