3Com MSR 30, MSR 50 manual Peer connect-interface IPv6 address family view

1246 CHAPTER 82: IPV6 BGP CONFIGURATION COMMANDS

Parameters ipv6-group-name: Name of a peer group, a string of 1 to 47 characters. ipv6-address: IPv6 address of a peer.

Description Use the peer capability-advertise route-refresh command to enable IPv6 BGP route-refresh.

Use the undo peer capability-advertise route-refresh command to disable the function.

By default, route-refresh is enabled.

Examples # Disable route-refresh of peer 1:2::3:4.

<Sysname> system-view [Sysname] bgp 100 [Sysname-bgp] ipv6-family

[Sysname-bgp-af-ipv6] peer 1:2::3:4 as-number 100

[Sysname-bgp-af-ipv6] undo peer 1:2::3:4 capability-advertise route-refresh

Syntax peer { ipv6-group-name ipv6-address } connect-interfaceinterface-type interface-number

undo peer { ipv6-group-name ipv6-address } connect-interface

View IPv6 address family view

Parameters ipv6-group-name: Name of a peer group, a string of 1 to 47 characters.

ipv6-address: IPv6 address of a peer.

interface-typeinterface-number: Specifies the type and name of the interface.

Description Use the peer connect-interfacecommand to specify the source interface for establishing TCP connections to an IPv6 BGP peer or peer group.

Use the undo peer connect-interfacecommand 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 loopback0 as the source interface for routing updates to peer 1:2::3:4.
