peer group (BGP-IPv4 unicast address family view) (IPv6)

Function

The peer group command adds a peer to a peer.

The undo peer group command deletes a peer from a peer group and all configurations of the peer.

By default, no peer group is created.

Format

peer peerIpv6Addr group peerGroupName

undo peer peerIpv6Addr group peerGroupName

Parameters

Parameter	Description	Value
peerIpv6Addr	Specifies the IPv6 address of a peer.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
peerGroupName	Specifies the name of a peer group.	The value is a string of 1 to 47 case-sensitive characters, spaces not supported.

Usage Guidelines

Usage Scenario

On a large-scale BGP network, there are a large number of peers and many of them have the same routing policies. To configure these peers, you have to repeatedly use some commands. In such a case, configuring peer groups can simplify configurations. If you intend to perform the same configuration on several peers, create and configure a peer. Then, add the peers to the peer group. The peers will inherit the configurations of the peer group.

Precautions

Peers with different AS numbers can be added to the same peer group. If a peer has an AS number, the peer keeps its own AS number after being added to a peer. If a peer has no AS number but the peer group to which the peer will be added has an AS number, the peer inherits the AS number of the peer group after being added to the peer group.

The members of a peer group can be configured with different route receiving and advertising policies.

The undo peer group command has the same function with the undo peer command and the undo peer enable command.

Example

# Create an IBGP peer group named test, and then add a peer to it.

<HUAWEI> system-view
[~HUAWEI] bgp 100
[*HUAWEI-bgp] group test
[*HUAWEI-bgp] peer 2001:DB8:1::1 as-number 100
[*HUAWEI-bgp] ipv4-family unicast
[*HUAWEI-bgp-af-ipv4] peer 2001:DB8:1::1 enable
[*HUAWEI-bgp-af-ipv4] peer test enable
[*HUAWEI-bgp-af-ipv4] peer 2001:DB8:1::1 group test
