Default Export Routing Policy for RIP

C

RIP (Routing Information Protocol) is a dynamic routing protocol used to exchange routing information within a network. When a RIP speaker receives a routing update, it applies a set of routing policies to determine which routes to accept and propagate to its neighbors.

The default export routing policy for RIP is option D, "Accept all direct routes." This means that by default, the router will advertise all directly connected routes to its RIP neighbors.

Directly connected routes are those that are learned through an interface, such as a LAN or WAN link. For example, if a router is directly connected to a subnet with IP address range 192.168.1.0/24, it will automatically generate a route for that subnet and advertise it to its RIP neighbors.

This default export policy can be modified using the policy language in Junos OS. You can create custom export policies to filter, modify, or prioritize the routes that are advertised by RIP.

In summary, the default export routing policy for RIP is to accept all direct routes. This means that the router will advertise all directly connected networks to its RIP neighbors by default, but this behavior can be changed using custom routing policies.
