[c-nsp] Catalyst 650x sup2 or sup32

[Jeff Meyers]

Hello list,

we're currently planning some ugprades for our network. We want to 
remove all Layer-3 edge functionality away from our Juniper routers to 
some Cisco 650x switch/router.
The requirements for this box are rather simple:

- redundante Management with a _very_ short fail-over time
- GigE right now is sufficient
- OSPF
- IPv4 and IPv6 routing in hardware
- only one OSPF database + all local routes + default-route of course
- ACLs of course for edge filters

Since our experience with those boxes is rather low, we are not sure 
what exactly we need. A sup32 seems to be a good choise but is a lot 
more expensive than e.g. a sup2. So will a sup2 do this job here? Which 
daughterboards would we need? Is a modern IOS available for this sup or 
is it even the same as those that are used on sup32 and sup720?

Does the sup2 support stateful fail-over, especially for ospf? Is 10G 
possible with a sup2? Do the following modules work with the sup2:

WS-X6516-GE-TX
WS-X6516-GBIC

Is there a fixed bandwidt assigned to each slot or is the(32GBit?) 
shared bus dynamically allocated to the linecards?



Thanks!
