RemarksEnter system view system-view —Enter BGP view bgp as-number RequiredEnter IPv6 address familyview ipv6-family —Specify the sourceinterface for establishingTCP connections to aBGP peer or peer grouppeer { ipv6-group-name |ipv6-address }connect-interfaceinterface-typeinterface-numberRequiredBy default, BGP uses theoutbound interface of thebest route to the BGPpeer as the sourceinterface for establishing aTCP connection.Note:z To improve stability and reliability, you can specify a loopback interface as thesource interface for establishing TCP connections to a BGP peer. By doing so, aconnection failure upon redundancy availability will not affect TCP connectionestablishment.z To establish multiple BGP connections to a BGP router, you need to specify on thelocal router the respective source interfaces for establishing TCP connections to thepeers on the peering BGP router; otherwise, the local BGP router may fail toestablish TCP connections to the peers when using the outbound interfaces of thebest routes as the source interfaces.5.3.6 Allowing the establishment of a Non-Direct EBGP connectionFollow these steps to allow the establishment of EBGP connection to a non-directlyconnected peer/peer group:To do...
