Allowing The Establishment Of A Non-Direct Ebgp Connection; Configuring A Description For An Ipv6 Peer/Peer Group - HP 4800G Series Configuration Manual

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.
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:
Enter system view
Enter BGP view
Enter IPv6 address family view
Allow the establishment of eBGP
connection to a non directly connected
peer/peer group
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.
