Note:
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.
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:
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
Caution:
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 connection with
loopback interfaces.
5.3.7 Configuring a Description for a Peer/Peer Group
Follow these steps to configure description for a peer/peer group:
To do...
system-view
bgp as-number
ipv6-family
peer { ipv6-group-name |
ipv6-address }
ebgp-max-hop
[ hop-count ]
Use the command...
