3.5.4 Binding an Interface with the VPN Instance
After associating an interface with a VPN instance, you can change the interface to a VPN
interface. As a result, packets that pass through the interface are forwarded according to the
forwarding information of the VPN instance, and such Layer 3 attributes as IP address and
routing protocol that are configured for the interface are deleted. These Layer 3 attributes need
to be re-configured if required.
Context
The configuration on the Hub-PE involves two interfaces or sub-interfaces: one is bound with
the VPN-in and receives the routes advertised by the Spoke-PE; the other is bound with the
VPN-out and advertises the routes of the Hub and all the Spokes.
Do as follows on the Hub-PE and all the Spoke-PEs.
