I'm sure this is an easy softball for someone on this list. Do IOS routers such as the ISRs, 7200s, etc support anything other than traditional STP? I'd like to set up RSTP for one particular redundancy design scenario involving a 2800 with an ESW HWIC and a pair of stacks 3750Es. I'm recommending that HW using STP (preferably rapid-STP) to shutdown the redundant link to the second 3750E. Simple enough and low-cost. I can't find any useful docs on cisco.com that refers to IOS routers and RSTP.

The other thought that just came to mind is Etherchannel support on the ESW ports in an ISR. Do they support Etherchannel? If so then that would eliminate the need for RSTP.

Thanks
 Justin
