As a cost cutting alternative - has anyone played with
the 2900 XL series using sub interfaces to turn them
into virtual router ports ?
"routing on a stick". As long as you understand that the aggregate
bandwidth can't be more than the port you hook too, fine.
On a 7500, you need your FE on a real VIP, not the legacy FE blade that
was the precursor to the VIP2. Although there is a later version that's
ISL capable, the performance is not there.
