7505 with an RSP4 is a supported configuration. It can be ordered as the
CISCO7505/4.
My first question is: Have you ever tried putting an RSP2 in a 7505? It
ships with an RSP, second, have you tried putting an RSP4 in a 7505? It
works too. Cisco isn't real happy about it, and of course I wouldn't
recommend it, but it works.Next, if your network is that busy, you honestly don't keep that
kind of spare/upgrade equipment around?-Deepak.
Thats my point. It often ISN'T easy. For example, say you've got a
7505 in one spot and find its getting killed. You can't put an rsp4 in
a 7505. You've got to replace the router. Anyone got any spare 7507s
or 7513s lying around? Chances are that if they do, its 2 or 3.Its actually going to be a bit more problematic to split the load
between two routers since that can mean notable changes in the
internal routing or the BGP tables. Not to mention calculating what
kind of traffic is going to pass BETWEEN the two routers.Straightforward, yes. Easy, no.
