I use 2811s in a couple of similar configurations. One of them
currently uses about 400M of the 768M ram with 4 BGP feeds and
"soft-reconfiguration inbound." Another with just one BGP feed and
soft-reconfiguration takes about 300M. Needs a minute or so to recover
from one of the BGP links dropping but otherwise it keeps up with my
light-weight traffic just fine. In both cases the packets are
cpu-switched and normal CPU load (when a link isn't collapsing or
returning) is under 10%.
