Re: Another question on rfc1918

aloha michael, i realize that good practice many not be general practice, but ... lsr is encouraged at routers bordering with bgp peers for debugging purposes, i.e. so that A may learn B's routing towards C without calling/writing/bothering B's engineers. but lsr really should be blocked at hosts, e.g. # grep lsr /etc/ipfw.rules add deny log all from any to any ipoptions ssrr,lsrr,rr i am not aware of a similar common use case for ssr. randy
