RE: Partial vs Full tables

Hi all,

Loose mode RPF will essentially drop traffic received on the interface if the router does not have any route for. (will not match a default or a discard route, at least in IOS-XR)

As Bill has pointed out, this may drop traffic from some peering networks that are not in the global routing table. Though one could argue that if a packet needs to be fragged it's typically closer to the edges rather than the transit/peering links.

No one has mentioned it , but you can also use an acl combined with urpf. You could even go so far as permiting everything and just using urpf for rtbh purposes. Brian
