Hi guys.



We're considering replacing our 7206VXR/NPE-400 (512MB RAM) with some newer
hardware.



We take a single full routing table, have (1) OSPF and (4) BGP peers, and
currently push about 70M aggregate.



We're considering a 2921 because it has 1GB RAM and can do 480k PPS / 245M
throughput compared with the NPE-400's 420k PPS / 215M.



What I'm not clear on is CPU speed. The NPE-400 looks like it's a 300MHz
processor. Does someone know how fast the 2921's CPU is?



Thanks,

Adam

we just this year went through similar migrations - we had 2 7206 w/npe
G2.  BGP 400K routes
replaced them with 3925s - which seemed overkill at the time - still is.

Internally as we are moving 10M to 1G circuits to new gear we are going
with 29xx and 4451s at the core ( we thought about the ASR and like its
performance, the 4451 emulates the ASR chip but the 4451 seems to be more
flexible in terms of features.

We hooked up to 2921 back to back and did some iperf/ftp traffic flows with
NAT and got well over 500Mb through it .
Your mileage of course will vary .. NAT, QOS, IPSEC, ....
