I wanted to know what things should be taken into consideration when deciding whether to create an L2 trunk between two distribution switches in a routed distribution layer.
I have 2 server farm access switches, each SINGLE-homed to one of the CatOS distribution switches and each server will be dual-homed. The distro switches are legacy CatOS/MSFC 6513 architectures, each running SRM with dual SUP 720s.
So, I will, of course, build an L3, routed link between distro switches to support redundancy, route summarization/aggregation and HSRP. I am wondering if it would be worthwhile to also create an L2 connection between the distro switches. What I am thinking is that it will be useful in the event that the routing engine in one of the switches dies,(lets say its in distro switch 1). Switch 1 will then be able to switch the traffic over a vlan that spans the trunk over to distro switch 2 for processing. No? I guess this is less of an issue when youre running high availability SUPs plus SRM mode in each switch.
What say ye? :-)
