Hi, I notice that there is a description of route selection algorithm:
The global best route selection algorithm is (roughly) as follows:
* Preferences of the routes are compared. * Source protocol instance preferences are compared. * If source protocols are the same (e.g. BGP vs. BGP), the protocol's route selection algorithm is invoked. * If source protocols are different (e.g. BGP vs. OSPF), result of the algorithm is undefined.
And I also notice that normally the configuration "Administrative Distance" that is mapped to preference under channel in bird is different between eBGP (default value 20) and iBGP (default value 200).
Hi No, default value is 200 for both EBGP and IBGP. Where did you noticed 20? -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
