[c-nsp] 7301 load

[Arie Vayner (avayner)]

Alex,

To tell you the truth, your utilization of this router is quite
impressive.
I would suggest you get another one (maybe 7201, which is stronger), and
start splitting the services a bit between the two routers...

Hi!

Our company is a city ISP and we have a 7301 router to connect our metro
network to Internet.
Router runs BGP with 10 peers, 3 of them are upstreams and provide us
with full routing table. Also it performs inter vlan routing in a
"router on a stick" manner(150 VLANs) and intra-AS routing(~600 subnets)
using an OSPF as IGP. 
Other features configured are DHCP-relay,authorized ARP, netflow-export,
traffic-shape(6 pipes), policy-routing(on 30 subinterfaces)  and ACL.
Only one of three routers gigabit ethernet interfaces currently in use. 
Currently we have CPU load between 75 and 95% and interface load
500-600Mb/s, 90-120 Kpps each direction. 
What do you think, is CPU load normal relative to interface load? If not
then which things should be checked to lower down CPU usage?

Thanks.

Alex.
