        **What is RIPv2?**

        RIPv2 (Routing Information Protocol version 2) is an enhanced version of RIPv1. It is a distance-vector
        routing protocol that supports classless routing and includes several improvements over RIPv1.

        **How is RIPv2 different from RIPv1?**

        * Supports Classless Routing - RIPv2 includes subnet mask information in updates.
        * Multicast Updates - Sends updates to 224.0.0.9 instead of broadcasting.
        * Authentication - Supports plain text and MD5 authentication.
        * More Efficient - Reduces unnecessary traffic with multicast and better loop prevention.

        **What metric does RIPv2 use?**

        RIPv2 uses hop count as its metric, just like RIPv1. The maximum hop count is 15.

        **What is the administrative distance of RIPv2?**

        The administrative distance is 120, same as RIPv1.

        **Does RIPv2 support VLSM and CIDR?**

        Yes, RIPv2 supports Variable Length Subnet Masking (VLSM) and Classless Inter-Domain Routing (CIDR), making it more flexible for IP address allocation.

        **What are the limitations of RIPv2?**

        * Still limited to 15 hops.
        * Slow convergence compared to modern protocols like OSPF or EIGRP.
        * Not ideal for large or complex networks.

        **What is the multicast address used by RIPv2?**

        RIPv2 uses the multicast address 224.0.0.9 to send routing updates.
