I was curious if route-map processing in BGP neighbor statements is done
in software or hardware on the 7600/rsp7203cxl and 7600/sup7203b.
Mostly looking at route-maps to define blocks to advertise, and set
communities, as well as perform actions based on communities (control
level of prepending to certain upstream peers(prepend 3x to provider A,
but 1x to provider C), or the exit point to upstream peers based on the
set communities(likely by setting next-hop ip for egress traffic)) and
wondering if this will have a significant impact on the CPU. Total bgp
routes are probably <50, and bandwidth through any one link is typically
<100mbit (each router has 3 links)
