Requirements for Configuring RIPv2 on an IPv4 Network Router

BD

To configure Routing Information Protocol version 2 (RIPv2) on a router in an IPv4 network, the following two requirements are necessary:

1. Enabling RIP on the router: The router needs to be configured to use RIP, which can be done by enabling the RIP routing process on the router. This allows the router to send and receive routing updates using RIP.

2. Allowing unicast updates for RIP: By default, RIP uses broadcast messages to send and receive routing updates. However, it is possible to configure RIP to use unicast updates instead, which can help conserve network bandwidth. To allow unicast updates for RIP, the router needs to be configured to use a unicast address as the destination address for RIP updates.

Therefore, the correct answers are B and D.

A. Enabling automatic route summarization: Automatic route summarization is a feature of some routing protocols that can help reduce the size of the routing table by summarizing multiple routes into a single, more general route. However, it is not a requirement for configuring RIPv2 on a router.

C. Enabling RIP authentication: RIP authentication is a security feature that can be used to ensure that routing updates are only accepted from trusted sources. However, it is not a requirement for configuring RIPv2 on a router.

E. Connecting RIP to a WAN interface: RIP can be used to exchange routing information between routers on a local network or across a WAN. However, connecting RIP to a WAN interface is not a requirement for configuring RIPv2 on a router.
