export route-policy evpn

Function

The export route-policy evpn command associates the VPN-IPv4 address family or VPN-IPv6 address family of a VPN instance with an export routing policy to filter routes to be advertised to the EVPN.

The undo export route-policy evpn command disassociates the VPN-IPv4 address family or VPN-IPv6 address family of a VPN instance with an export routing policy.

By default, the VPN-IPv4 address family or VPN-IPv6 address family of a VPN instance is not associated with any export routing policy.

Format

export route-policy policy-name evpn

undo export route-policy policy-name evpn

Parameters

Usage Guidelines

Usage Scenario

By default, the VPN IPv4/IPv6 address family of a VPN instance adds all VPN targets in the export VPN target list to routes to be advertised to the EVPN. To control route export more precisely, run the export route-policy evpn command to associate the VPN IPv4/IPv6 address family with an export routing policy and set attributes for eligible routes.

Prerequisites

An RD has been configured for the VPN instance IPv4/IPv6 address family using the route-distinguisher command.

Configuration Impact

If the command is run more than once, the latest configuration overrides the previous one.

The export routing policy configured using the export route-policy evpn command does not affect the export routing policy applied to the VPN instance using the export route-policy command.

Precautions

If the specified routing policy does not exist, run the route-policy command to create the routing policy.

Example

# Associate the VPN instance IPv4 address family of a VPN instance named vrf1 with an export routing policy named policy-2 to filter routes to be advertised to the EVPN.
