Command Manual – IPv6 Routing
H3C S7500E Series Ethernet Switches
ipv6-address: IPv6 address of a peer.
interface-type interface-number: Specifies the type and name of the interface.
Description
Use the peer connect-interface command to specify the source interface for
establishing TCP connections to an IPv6 BGP peer or peer group.
Use the undo peer connect-interface command to restore the default.
By default, BGP uses the outbound interface of the best route to the IPv6 BGP
peer/peer group as the source interface for establishing a TCP connection.
Note that:
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.
Examples
# Specify loopback 0 as the source interface for routing updates to peer 1:2::3:4.
