Configure Interfaces for Layer 3 VPNs

When you configure the Layer 3 VPN interfaces at the [edit interfaces] hierarchy level, you must also configure family inet when configuring the logical interface:

[edit interfaces]

interface-name {

    unit logical-unit-number {

        family inet;

    }

}

 If you downgrade JUNOS to version 5.5 or earlier, the Layer 3 VPN configuration might become invalid. Layer 3 VPN interfaces between PE and CE routers formerly required the family mpls statement.
