Traffic Flow from the Internet to the VPN Overview
When traffic flows from the Internet to a VPN, the traffic arrives at the PE router on an interface in the global context. BGP performs a lookup in the global IP routing table, which normally does not contain VPN routes. You can use one of the following methods to advertise public VPN routes to the Internet (get the routes into the global routing table) and thus enable traffic flow from the Internet to those VPNS.
- Manually create shared interfaces in the parent VR and manually add static routes to those shared interfaces. See VRF–to–VR Peering Overview for more information.
- Export VPN routes to the global BGP RIB. See Understanding Route Distribution for a VRF using Maps.
