Checking the RIB for RIP, OSPF, EIGRP, BGP, & IS-IS

RIP – “sh ip rip database”

OSPF – OLD > “sh ip ospf database”
NEW > “sh ip ospf rib detail”

EIGRP – “sh ip eigrp topology all-links”
* You can see routes that failed the feasibility check.

BGP – “sh ip bgp”
* You can see the RIB failures and the reason using this command: “show ip bgp rib-failure”

IS-IS – “sh isis database”
