[c-nsp] 7206vxr/300 vs 7507/rsp4

[Eric Kagan]

I am looking for some feedback from true experiences.  I tried to find some
archive threads on this but could not find anything direct. Does anyone have
any direct comparisons of actual performance between a 7507/RSP4 and a
7206VXR/300 and/or 7026 non VXR/200 NPE ?  (Like you had a 7200 running a
job at XX CPU, etc and replaced it with similar 7500 config and it ran aat
XX CPU...)  I am looking to run a border router (4-5 BGP Full Feed w/ peers)
with 2 or 3 Fast Ethernet handoffs sustaining around 60-80MB/sec and wants
thoughts on which device is best for this job.  I hear a lot of xx router is
good for circuit aggregation, xx is good for large packet / throughput, etc
and want to take this in to consideration.  Also, if anyone is running HSRP
over ISL (Cisco doc link
http://www.cisco.com/en/US/products/sw/iosswrel/ps1826/products_configuratio
n_guide_chapter09186a00800880fa.html#xtocid1748516)  I would be curious of
any gotchas or thoughts for this equipment in this configuration as well.
If I read it correctly, I can have 2 router / switch ISL setups with the 2
switches connected via a trunk port between them.  I should then be able to
hand a device a single ethernet (or dual) and have failover redundancy if
there is a router problem (or if dual feeds a switch problem)....Offline
comments welcome.
 
Thanks
