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.
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:

Allow the establishment of eBGP
connection to a non directly connected
peer/peer group
peer { ipv6-group-name |
ipv6-address }
ebgp-max-hop [ hop-count ]
Required
Not configured by
default.
In general, direct links should be available between eBGP peers. If not, you can use the peer
ebgp-max-hop command to establish a multi-hop TCP connection in between. However, you need not
use this command for direct eBGP connections with loopback interfaces.
