If I look for BGP info on an IP using one of the Looking Glass sites
(specifically Mae-East) does the number of entries returned mean anything?
I have noticed that sometimes there are five or six entries and sometimes
only one or two. The number of upstream connections is two. If only one
entry exists, then is BGP broken? For example:
BGP routing table entry for 216.91.141.0/24, version 7089796
Paths: (1 available, best #1)
Advertised to peer-groups:
rr-pop
Advertised to non peer-group peers:
198.32.187.122
6347 20068
64.241.88.17 (metric 175301) from 165.117.1.110 (165.117.1.110)
Origin IGP, metric 4294967294, localpref 100, valid, internal, best
Community: 2548:196 2548:229 2548:666 3706:168 6347:1002 6347:3000
To me that implies that there are no alternate routes, and so no BGP on this
route. Also, if there are more than two routes does that mean the routes
are better connected?
What is the best resource for learning more about BGP?
Thanx,
Anil Gupte
