Overview PBR Tools

A routing policy can change properties or reachability of a route so as to change the routing information or change the paths that the data flow passes. A routing policy is mainly applied in the following aspects:

• Sets route properties: Sets the required route properties for the routes that match the routing policy.
• Controls route advertisement: When a routing protocol advertises route, it advertises only the routes that meet the requirements.
• Controls route receiving: When a routing protocol, it receives only the routes that meet the requirements so as to control the number of routes and improves the network security.
• Controls route redistribution: When a routing protocol redistributes external routes, it introduces only the routes that meet the requirements. A routing policy tool can also be used to set some properties for the external routes that are introduced.

Key-chain is a password management tool. It provides authentication passwords for the routing protocol to authentication protocol packets.
