I'm doing this for a normal "internet" routing table. What are you
referring to that could make iBGP so CPU intensive ? I'd think that
iBGP would be one of the last causes of CPU burning, except during
restart of a major peer. And that's only on old processors, too,
PRP-2s are quite snappy at it.

Do you mean there are implementation of BGP that don't allow
route-maps (or equivalent) in iBGP sessions ?
