Reverse route injection is a feature of some VPN solutions that dynamically injects routing information from the remote endpoint into the local routing table. This allows the local network to know how to reach the remote network through the VPN tunnel.
When a VPN tunnel is established, the remote VPN gateway sends the local VPN gateway the routing information for the remote network. The local gateway then injects that routing information into the local routing table so that any traffic destined for the remote network will be routed through the VPN tunnel.
Reverse route injection is often used in conjunction with dynamic routing protocols like OSPF or BGP, which allow the VPN gateways to exchange routing information and automatically update the local routing table with the latest network topology information.
Option A, policy-based routing, is a method of routing that allows different routing policies to be applied to different types of traffic. It is not directly related to the installation of network routes for remote tunnel endpoints.
Option B, CEF (Cisco Express Forwarding), is a packet-forwarding technique used by Cisco routers that improves packet forwarding performance. It is not directly related to the installation of network routes for remote tunnel endpoints.
Option D, route filtering, is a method of controlling the routing of network traffic by selectively filtering out certain routes. It is not directly related to the installation of network routes for remote tunnel endpoints.
