3.5.4 Associating an Interface with the VPN Instance
Context
The configuration on the Hub-PE involves two interfaces or sub-interfaces: one is bound to the
VPN-in and receives the routes advertised by the Spoke-PEs, the other is bound to the VPN-out
and advertises the routes of the Hub and all the Spoke sites. The following is the configuration
procedure.
The VPN instance needs to be associated with the interface connecting to the CE. After being
associated with a VPN instance, the interface becomes a VPN interface. Packets sent to this
interface are forwarded according to the forwarding information of the VPN instance.
Do as follows on every Spoke-PE and Hub-PE.
