3. Troubleshooting Functional Failures in Operation803.10.3 No BGP4+ Routing Information ExistsIsolate the problem according to the failure analysis method listed below if BGP4+ route information does not exist inthe displayed route information acquired by this system.Table 3-37: BGP4+ Failure Analysis MethodNo. Troubleshooting Steps and Command Action1 Check the BGP4+ peer status.show ipv6 bgp neighborsGo to No. 2 if the peer status is other than Established.Go to No. 3 if the peer status is Established.2 Check to see if the BGP4+ setting is correct inconfiguration.Go to No. 3 if the configuration is correct.Correct the configuration if it is not correct.3 Check to see if the BGP4+ route is learned.show ipv6 bgp received-routesGo to No. 4 if the route exist but it is not in active status.Go to No.5 if no route exist.4 Check to see if routing information for the nexthop address resolution in BGP4+ exist.show ipv6 routeGo to No.5 if the route information for the next hop address resolutionexists.When no routing information for the next hop address resolution exist,perform the protocol failure analysis to learn the routing information.5 Confirm that the routing are not filtered byreferring to the configuration.Check to see if the neighboring router advertises the BGP4+ route.Correct the configuration if it is not correct.
