Re: default-information originate route-map

Hmmm yeah, that works. But I think this (using "track ip route
reachability") is a touch tidier:

track 1 ip route 0.0.0.0 0.0.0.0 reachability
!
ip route 1.1.1.1 255.255.255.255 Null0 track 1
!
access-list 72 permit 1.1.1.1
!
route-map BLAH
 match ip address 72
!
router rip
 default-information originate route-map BLAH

cheers,
Dale
