Is there an easy way to see which iBGP routes are not being selected due to next-hop not being in IGP?
I have suggested more than a few times to vendors that the command: show bgp ipv4 unicast 100.10.0.0/16 why-chosen Would be insanely useful. Yes, you can recreate the 7+ BGP decision steps in your mind by running a pile of show commands, but when you're trying to figure out several odd routes at the same time this is very hard to keep in your head and very labor intensive. The box knows why it chose the route, and should be able to show that to you. Of course most boxes can't show you outgoing BGP communities either. *sigh* Is it really too hard to ask to get a show bgp neighbor ... advertised that shows ALL of the attributes? -- Leo Bicknell - bicknell () ufp org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
