People,
Halabi says sub-AS's are not counted in calculating the path length, therefore
on his AS border routers he has confgured a filter-list to allow only locally o
riginated routes ( ie ^$ ).
Problem:- when I try this I find that the border routers will NOT advertise any
routes they have learnt from the other sub-AS eg the bdr rtr in sub-AS 65060
will not advertise to its EBGP peer any routes originated in sub-AS 65050 ie th
e ones with just (65050) in the path.
When I remove the ^$ filter-list it does. So I either have a dodgy level of IOS
11.2(18) or Halabi's statement is not true.
Any comments ?
