3. Create an IPv4 BGP peer and specify its AS number.

peer ip-address as-number as-number

By default, no IPv4 BGP peer is created.

4. (Optional.) Configure a description for a peer.

peer ip-address description description-text

By default, no description is configured for a peer.

5. Create the BGP IPv4 unicast address family or BGP-VPN IPv4 unicast address family and enter its view.

address-family ipv4 [ unicast ]

By default, the BGP IPv4 unicast address family or BGP-VPN IPv4 unicast address family is not created.

6. Enable the router to exchange IPv4 unicast routing information with the specified peer.

peer ip-address enable

By default, the router cannot exchange IPv4 unicast routing information with the peer.

Configuring an IPv6 BGP peer

Step

Command

Remarks

1. Enter system view.

system-view

N/A

2. Enter BGP view or BGP-VPN instance view.

  • Enter BGP view:bgp as-number

  • Enter BGP-VPN instance view:

    1. bgp as-number

    2. ip vpn-instance vpn-instance-name

N/A

3. Create an IPv6 BGP peer and specify its AS number.

peer ipv6-address as-number as-number

By default, no IPv6 BGP peer is created.

BGP can use an IPv6 link-local address to establish a peer relationship with a peer when the following conditions exist:

  • The IPv6 link-local address belongs to the interface directly connected to the local router.

  • The peer connect-interface command is configured on the peer to specify the interface as the source interface.

4. (Optional.) Configure a description for a peer.

peer ipv6-address description description-text

By default, no description is configured for a peer.

5. Create the BGP IPv6 unicast address family or BGP-VPN IPv6 unicast address family and enter its view.

address-family ipv6 [ unicast ]

By default, the BGP IPv6 unicast address family or BGP-VPN IPv6 unicast address family is not created.

6. Enable the router to exchange IPv6 unicast routing information with the specified peer.

peer ipv6-address enable

By default, the router cannot exchange IPv6 unicast routing information with the peer.
