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 a BGP connection, you need to specify on the local router the source interface for
establishing the TCP connection to the peer on the peering BGP router; otherwise, the local BGP
router may fail to establish TCP connection to the peer when using the outbound interface of the
best route as the source interface.
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:
To do… Use the command… Remarks
Enter system view system-view
—
Enter BGP view bgp as-number
—
Enter IPv6 address family view ipv6-family
—
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.
Configuring a Description for an IPv6 Peer/Peer Group
Follow these steps to configure description for an IPv6 peer/peer group:
To do… Use the command… Remarks
Enter system view system-view
—
Enter BGP view bgp as-number
—
Enter IPv6 address family view ipv6-family
—
Configure a description for an
IPv6 peer/peer group
peer { ipv6-group-name |
ipv6-address } description
description-text
Optional
Not configured by default.
