To disable, use the no neighbor {ipv6-address | peer-group-name} fall-over command.Parameters ipv6-address Enter the IPv6 address in the x:x:x:x::x format.NOTE: The :: notation specifies successive hexadecimalfields of zeros.peer-group-name Enter the name of the peer group.Defaults Disabled.Command Modes ROUTER BGPCommand History Version Description9.9(0.0) Introduced on the C9010.9.2(1.0) Introduced on the Z9500.8.2.1.0 Introduced on the E-Series ExaScale.7.4.1.0 IntroducedUsage Information When you enable fall-over, BGP keeps track of IP or IPv6 reachability to the peerremote address and the peer local address. Whenever either address becomesunreachable (for example, no active route exists in the routing table for peer IP or IPv6destination/local address), BGP brings down the session with the peer.RelatedCommandsshow ip bgp neighbors – displays information on the BGP neighbors.neighbor filter-listConfigure a BGP filter based on the AS-PATH attribute.C9000 SeriesSyntax neighbor {ipv6-address | peer-group-name} filter-list as-path-name{in | out}To delete a BGP filter, use the no neighbor {ipv6-address | peer-group-name} filter-list as-path-name {in | out} command.Parameters ipv6-address Enter the IPv6 address in the x:x:x:x::x format.NOTE: The :: notation specifies successive hexadecimalfields of zeros.Border Gateway Protocol 603
