Hi everybody
"* " means Valid in BGP . What does BGP consider before declaring a route as valid?
For example, below, R1 is receiving an update about 6.0.0.0/8 from its ibgp peer. The next hop is 196.196.196.1 is not reachable by R1 but yet R1 still considers a valid route ( * is attached next to 6.0.0.0/8).
R1#show ip bgp
BGP table version is 8, local router ID is 196.196.196.1
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
*i6.0.0.0 195.195.195.5 0 100 0 6 i

C 196.196.196.0/24 is directly connected, Serial0/1
R 6.0.0.0/8 [120/1] via 188.188.188.2, 00:00:24, Serial0/0
R 189.189.0.0/16 [120/1] via 188.188.188.2, 00:00:24, Serial0/0
188.188.0.0/24 is subnetted, 1 subnets
C 188.188.188.0 is directly connected, Serial0/0
S 11.0.0.0/8 is directly connected, Serial0/0
Thanks and have a great weekend.
