[c-nsp] Question BGP Table

[Olivier CALVANO]

Hi

i see in my network in sh ip bgp xxx:

BGP routing table entry for xx.xx.xx.xx/30, version 534149
Paths: (2 available, best #1, table default, not advertised to EBGP peer,
RIB-failure(17))
  Not advertised to any peer
  Local


on 3x /30, on the same router, i have: "RIB-failure(17)"

and in logs:  %IPRT-3-RIB_LOOP: Resolution loop formed by routes in RIB
(it's a cisco 7201)

Anyone know what is this failure ?

regards
Olivier.
