BGP table status codes
The following is an example of a BGP table:
R1#show ip bgp BGP table version is 2, local router ID is 192.168.13.1 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 * 4.4.4.4/32 192.168.13.3 0 3 4 i *> 192.168.12.2 0 2 4 i
The meaning of the status codes can be found below:
- "s" for suppressed: BGP knows about this network but is not advertising it, usually because it is part of a summarized route.
- "d" for dampened: BGP can stop advertising a network that flaps (goes up and down) too often until it is stable for a period of time.
- "h" for history: BGP knows about this network but does not currently have a valid route to it.
- "*" for valid: The route is valid and BGP is able to use it.
- ">" for best: The route has been selected as the best path and has been installed in the routing table.
- "i" for internal: The route was learned from an iBGP peer.
- "r" for RIB failure: The route was advertised to BGP but it was not installed in the IP routing table. This might be because of another protocol having the same route with a better administrative distance.
- "S" for stale: Used with nonstop forwarding to indicate that the route is stale and needs to be refreshed when the peer is reestablished.
