peer enable (BGP-Flow VPN instance IPv6 address family view)

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, the function is disabled.

Format

peer { ipv4-address | ipv6-address } enable

undo peer { ipv4-address | ipv6-address } enable

Parameters

Parameter	Description	Value
ipv4-address	Specifies the IPv4 address of a peer.	It is in dotted decimal notation.
ipv6-address	Specifies the IPv6 address of a peer.	It is in the format of X:X:X:X:X:X:X:X.

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.

Configuration Impact

Enabling or disabling a BGP peer in an address family, for example, running the peer enable command or the undo peer enable command in a VPNv4 address family, causes teardown and re-establishment of the BGP connection of the peer in other address families.

Example

# Enable a BGP device to exchange routes with a specified peer.
