Which statements correctly describe route summarization as presented in the material? Select ALL that apply.

### Why this is right - **Routers can summarize contiguous networks**: the material explicitly describes summarizing contiguous routes. - **A summary can reduce the number of routes another router needs to keep**: one advertisement can represent several routes. - **An advertised summary must cover the intended networks**: otherwise the neighbor would not receive a route representing those destinations correctly. ### The concept Route summarization concerns routing information, not traffic authorization. A summary gives a router a broader destination prefix for forwarding. Security policies, by contrast, decide whether traffic is permitted. The slide's example says that one router can advertise a summary so its neighbor uses one route for several networks, simplifying routing tables. ### The other options - **D. A summary route is a security policy that permits traffic**: a route helps select where packets go; it does not grant permission through a firewall. ### Terms - **IP**: Internet Protocol. The network-layer protocol used to address and forward packets. ### Remember Routes select a path; security policies decide whether traffic is allowed.
