peer enable (BGP)
Function
The peer enable command enables a BGP device to exchange routes with a specified peer or peer group in the address family view.
The undo peer enable command disables a BGP device from exchanging routes with a specified peer or peer group.
By default, only the peer in the BGP IPv4 unicast address family view is automatically enabled.
Format
peer { group-name | ipv4-address | ipv6-address } enable
undo peer { group-name | ipv4-address | ipv6-address } enable
Parameters
| Parameter | Description | Value |
|---|---|---|
| group-name | Specifies the name of a peer group. | The name is a string of 1 to 47 characters without any space. It is case-sensitive. |
| ipv4-address | Specifies the IPv4 address of a peer. | It is in dotted decimal notation. |
| ipv6-address | Specifies the IPv6 address of a peer. | The prefix is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X. |
ipv4-address is valid only in the BGP view, BGP-IPv4 unicast address family view, BGP-IPv4 multicast address family view.
ipv6-address is valid only in the BGP-IPv6 unicast address family view.
Views
BGP view, BGP-IPv4 unicast address family view, BGP-IPv4 multicast address family view, BGP-IPv6 unicast address family view
Usage Guidelines
Usage Scenario
By default, only peers in the BGP IPv4 unicast address family are automatically enabled. After the peer as-number command is used in the BGP view, the system automatically runs the peer enable command to enable a peer. In other address family view, however, a peer must be enabled manually.
After the undo default ipv4-unicast command is run, the peer enable command needs to be run in the BGP view or the BGP-IPv4 unicast address family view to enable the IPv4 unicast address family for the created BGP peer.
