Usage Guidelines

Usage Scenario

To allow the system to use the VPN instance delivered by the RADIUS server or through a CoA message for Layer 3 static users, run the layer3-subscriber vpn-instance switch enable command.

After this command is run, the HW-VPN-Instance attribute delivered through a RADIUS authentication response packet or CoA message is applied to Layer 3 static users. If export host-route is configured, routes will be advertised after the VPN instance is changed for Layer 3 static users.

Precautions

The layer3-subscriber vpn-instance switch enable command takes effect only for subsequent Layer 3 static users.
