Even with a RIP failure, the result of "show ip bgp neigh adv" showed that the route having a R flag was advertised. Cisco says that it is not advertised.
Any Comments?
=====================================
Quoted:
Q. What does r RIB-Failure mean in the show ip bgp command output below?
R1> show ip bgp
BGP table version is 5, local router ID is 200.200.200.1
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
r> 6.6.6.0/24 10.10.13.3 0 130 0 30 i
*> 7.7.7.0/24 10.10.13.3 0 125 0 30 i
When BGP tries to install bestpath prefix into Routing Information Base (RIB), i.e., the IP Routing table, RIB might reject the BGP route due to any of the following reasons:
Route with better administrative distance already present in IGP, for example, if a static route already exists in IP Routing table.
Memory failure.
The number of routes in VPN routing/forwarding (VRF) exceeds the route-limit configured under the VRF instance.
In such cases, the prefixes that are rejected for the above reasons are identified by r RIB Failure in the show ip bgp command output and are not advertised to the peers. This feature was first made available in Cisco IOS Software release 12.2(08.05)T.
