My suggestion is to set up the access switches with 2 GBICs. One for Distro switch B and one for Distro switch C. If one of the Distro switches fail, you will automatically be routed to the other Distro switch. Again, make sure you're trunking between the links so any VLANs will still work. Make sure the specific ports for the Access Layer uplinks are set to the VLAN that you want. If the one dies, then the other will kick in. You can apply different weight to the links if you want to try to balance the traffic between the two switches (probably a smart idea).
How big is this network?? ccie1ab -----Original Message----- From: Thomas N.

[7:25028] Hi Group, I have this scenario and wonder if it is possible to setup the topology with redundancy. I have a CAT 6509 acting as the core switch (say switch A), and 2 other CAT 6506 acting as the distribution switches (say switch B and C). Both switch B and C have fiber uplinks to core switch A. Switches A and B also have a redundant fiber between them. Regarding the hardware, The core 6509 has 2 supervisor engines with dual MSFCs. The two 6506 have only one supervisor engine and their MSFC DO NOT do routing at all. My concern/question is that if the supervisor engine of one of the distribution 6506 died, can access switches attached to this 6506 re-route to the redundant link? I doubt this will work because the the supervisor engine of the 6506 has all the configuration (including vlans) for the ports/trunks attached to access switches died. Is there any way to to set them up so that if the supervisor engine on one distribution 6506 dies, all ports/trunks on this 6506 can still be OK with redundant link? Putting dual supervisor engines on each 6506 will be my last solution. Thanks All! Thomas N.
