[c-nsp] PA-FE-TX, PA-FE-TX/ISL, PA-2FE-TX, PA-2FE-TX/ISL

[Joe Maimon]

I would stay far far away from the 2 port FE port adapters, no matter 
what they say on them.

I would stick with VIP2-50 (or higher) with 128DRAM and only port 
adapters that work well in there. Only VIP2-50 (or better) and RSP in 
the chassis. Nothing else.

Use a cheap catalyst switch like the 2950 or 3524XL and port-channels. 
The router is cabled only to the switch. Everything is cabled only to 
the switch. Use vlans for fanout.

This should be relatively stable for the rsp platform and give you the 
best throughput and flexibility. Also it is dirt cheap.

If you are shopping the used market, you may be better off with the 7200 
series. The 7500 isnt worth the juice it sucks and even when it was 
supported, it was an abysmal experience.
