Wondering if someone can help out with a 6509 redundancy question. I have read so much information that It has all become a blurr.
We have two 6509's each with dual SUP2/MFSC's side by side in our core. They are in Hybrid mode with 8.3 (6) software.
What we are trying to accomplish is to have good redundancy and failover.
So far we have gotten both supervisors configured with HA and redundancy in single router mode. The config's are copying fine and the sh mod shows that we have a standby and active sups.
What we would like to do in a maintenance window is test the failover capability and ensure that ii is working as desired.
How does the physical connectivity work, we were assuming that we could just criss cross the GBIC's on the Sups to ensure that no matter what the failover situation, the active sup would have a path to the other . When we attempted this it appears as if the GBIC on the standby sup is active ? Is this something to worry about?
Or is an Etherchannel solution the better option. ?
If you need any further clarification I can provide more details.
Thanks for you time
