5.3.5 Specifying the Source Interface for Establishing TCP Connections
Follow these steps to specify the source interface for establishing TCP connections to a
BGP peer or peer group:

Specify the source
interface for establishing
TCP connections to a
BGP peer or peer group
peer { ipv6-group-name |
ipv6-address }

interface-number
Required
By default, BGP uses the
outbound interface of the
best route to the BGP
peer as the source
interface for establishing a
TCP connection.
 Note:
z To improve stability and reliability, you can specify a loopback interface as the
source interface for establishing TCP connections to a BGP peer. By doing so, a
connection failure upon redundancy availability will not affect TCP connection
establishment.
z To establish multiple BGP connections to a BGP router, you need to specify on the
local router the respective source interfaces for establishing TCP connections to the
peers on the peering BGP router; otherwise, the local BGP router may fail to
establish TCP connections to the peers when using the outbound interfaces of the
best routes as the source interfaces.
5.3.6 Allowing the establishment of a Non-Direct EBGP connection
Follow these steps to allow the establishment of EBGP connection to a non-directly
connected peer/peer group:
