Richard,
So are you saying if you want to redistribute an OSPF external route and you match it with a prefix-list through a Route Map, you don't need to specify the "external" keyword even if the route specifically matched is external?
Thanks,
Ken

I believe this is for ospf although for isis it's a good idea to be as
specific as possible too.
So for ospf, the command "redistribute ospf 2 match internal external 1
external 2" can be used. But the recommended way is to explicitly state the
network one wants to redistribute into BGP with a prefix-list and a
route-map. Here the "match internal external " is not needed,

Hey Richard,
Good Tip - That's just the sort of thing I imagined when starting this
thing.
But, couldn't that tip be more generalized ie. when redist ospf into any
prot or is this specific to redist into BGP only?
