Parameter route-policy: Name of the export routing policy for the VPN instance, a string of 1 to 19 characters.

Description Use the export route-policycommand to apply an export routing policy to a VPN instance.

Use the undo export route-policycommand to remove the application.

You can configure an export routing policy when a finer control on the VPN instance routes to be redistributed is required, that is, when the control provided by the extended community attribute is not enough. An export routing policy may deny routes that are permitted by the export target attribute.

By default, all VPN instance routes permitted by the export target attribute can be redistributed.

Example # Apply export routing policy poly-1 to VPN instance vpn1.

<Sysname> system-view

[Sysname] ip vpn-instance vpn1

[Sysname-vpn-instance-vpn1] export route-policy poly-1
