I have some more questions about configureRouter My inet-rtr object: peer: BGP4 198.32.245.8 asno(AS13657) My aut-num object: import: from AS13657 198.32.245.8 at 198.32.245.49 accept <^AS13657 AS13657:AS-CUSTOMERS* $> AND AS13657 AND AS13657:AS-CUSTOMERS When I run the inet-rtr object through configureRouter, I get the correct as-path list as per the import attribute's accept policy filter, however it's not generating the proper prefix information. All it's generating is: no ip prefix-list pl100 ip prefix-list pl100 permit 199.246.110.0/23 ip prefix-list pl100 deny 0.0.0.0/0 le 32 That prefix has an origin of one of the AS' inside the as-set referenced above. The number of route objects with origins of AS13657 or origins of AS' inside AS13678:AS-CUSTOMERS is far more than the single prefix listed above. The idea of what I'm trying to do above should work, right? Generating as-path info from the as-path policy then generating the prefix info shouldn't be a problem, correct? Can anyone see anything wrong with what I'm trying to do? Anyone know of a better way to do it?
