BGP next-hop

[hj1980 at gmail.com (Heath Jones)]

Hi all,

Is there an easy way to see which iBGP routes are not being selected
due to next-hop not being in IGP?

Before and after IGP route added shown below, note both are marked as valid..

-- BEFORE IGP--
AS5000_LA#show ip bgp
BGP table version is 5, local router ID is 10.0.0.5
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
             r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

  Network          Next Hop            Metric LocPrf Weight Path
* i100.10.0.0/16    10.0.0.10                0    100      0 2000 3000 ?
*>                  10.0.0.6                               0 1000 3000 3000 ?

-- AFTER IGP--
AS5000_LA#show ip bgp
BGP table version is 6, local router ID is 10.0.0.5
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
             r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

  Network          Next Hop            Metric LocPrf Weight Path
*>i100.10.0.0/16    10.0.0.10                0    100      0 2000 3000 ?
*                   10.0.0.6                               0 1000 3000 3000 ?

ps. I've posted this to cisco-nsp also (a day ago) - so apologies in
advance if you are on both and seeing it twice.
