peer as-number (for a BGP peer)

Use peer as-number to create a BGP peer and specify its AS number.

Use undo peer to delete a BGP peer.

Syntax

peer { ip-address | ipv6-address } as-number as-number

undo peer { ip-address | ipv6-address }

Default

No BGP peer is created.

Views

BGP view, BGP-VPN instance view

Predefined user roles

network-admin

mdc-admin

Parameters

ip-address: Specifies the IP address of a peer.

ipv6-address: Specifies the IPv6 address of a peer.

as-number: Specifies an AS number for the peer, in the range of 1 to 4294967295. If the AS numbers of the peer and the local router are the same, the peer is an IBGP peer. If they are different, the peer is an EBGP peer.

Usage guidelines

You can also create a peer and add it to a peer group by using the peer group command.

To modify the AS number of a peer, do not execute the peer as-number command repeatedly. Instead, you must first delete the peer and configure it again.

After you create a peer, you must use the peer enable command to enable BGP to exchange routing information with the specified peer.

Examples

# In BGP view, create BGP peer 1.1.1.1 and specify its AS number as 100.

<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] peer 1.1.1.1 as-number 100

# In BGP-VPN instance view, create BGP peer 1::1 and specify its AS number as 100.

<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] peer 1::1 as-number 100
