Network Next Hop Metric LocPref Weight Path
* > 2.2.2.0/24 192.168.23.2 0 100 0 i
The * means that this is a valid route and that BGP is able to use it.
The > means that this entry has been selected as the best path.
i - through iGP, with network command
? - redistibution
e - will never see (refered to EGP)
supressed: BGP knows the network but won’t advertise it, this can occur when the network is part of a summary.
damped: BGP doesn’t advertise this network because it was flapping too often (network appears, disapears, appears, etc.) so it got a penalty.
history: BGP learned this network but doesn’t have a valid route at the moment.
RIB-failure: BGP learned this network but didn’t install it in the routing table. This occurs when another routing protocol with a lower administrative distance also learned it.
stale: this is used for non-stop forwarding, this entry has to be refreshed when the remote BGP neighbor has returned.
BGP table version - every time the best path changes this number will increase
