Hello,
I'm currently using a routing policy to force anything from 209.251.30.20 to
next-hop "Sprint", and anything from 209.251.30.21 to next-hop "UUnet". Once
we got up to about 60Meg/sec on a 300Mhz VXR I'm at around 80% CPU. Is there
a better way of doing this? See below for our current config.
I noticed with traceroute that I can use the -g switch to "loose source
route gateway", letting me choose the gw I want to use. This seems to work
for a few hops and then the traceroute dies. Is it possible to tell the
cisco to use the gateway I specify (with the -g option), rip out any special
header info that the -g put in the packet, and send it upstream? That way I
could get rid of the route policies and bring the CPU back down to something
usable?
Thanks,
Jason
