table-map/bgp/ospf/origin code question. I'm having some trouble
getting it to work. r1 has a loopback 1.1.1.1
and has a network statement in BGP for it, i'm taking the bgp routes,
putting them into ospf and trying to tag them (with origin code) and
then when that route makes it over to r3, trying to read the tag and set
it again so it shows "i" and not incomplete but I can't seem to get the
external tag data into ospf.
Here's the setup..
1.1.1.1 (lo1 in BGP as 1) R1---ospf0----r2----ospf0------r3(3.3.3.3 in
bgp as 3)
here's the relevant configs
