2 BGP links with different path to the same ASes question
Hello nanog, Supose that we got network: AS 1 ---- iBGP ---- AS 1 | link 1 | link 2 | | AS 2 ---- iBGP ---- AS 2 and now, we want on one of those links (link 1) - setup only peering session and on (link 2) - start normaln internet tranis and if we pay for internet transit and not pay for peering, our idea is: - send peering IP packets via link1 - send packets from internet via link2 only way that i can see is the usage of source-route PS: assume that networks of AS1 and AS2 are big and meshed networks and there is need for set up a lot of acls and routemaps and take them all up of date! any better hints ? -- Adam Obszyński

2001 AD AS1: Someone set us up the PVC AS1: we got network: AS1: peer maker turn on AS1: It's you! AS2: how are you nanog !! AS2: All your transit are belong to us AS2: You are on the way to source-routing AS2: You have no chance to survive; make your BGP AS1: What you say? AS2: Ha ha ha .... AS1: Captain!! AS1: Take off every 'ACL'!! AS1: Move 'ASN'. :) Yes, AS2 will most likely need source routing to keep your inbound transit traffic traffic off the 'peering' link. -- The comments and opinions expressed herein are those of the author of this message and may not reflect the policies of the Martin County Board of County Commissioners.
