■ Interface view
Description RIP-2 has 2 transmission modes: broadcast and multicast. Multicast is the default
mode. The multicast address in RIP-2 is 224.0.0.9. One of the advantages of multicast
mode is that the hosts that do not run RIP in this network will not receive the
broadcast packets. Additionally, hosts running RIP-1 will be prevented from receiving
and processing the RIP-2 routes with subnet masks.
When the interface specifies the use of RIP-1, only RIP-1 and RIP-2 broadcast packets
will be received. In this case, RIP-2 multicast packets will be rejected. When the
interface is specified to use RIP-2 multicast, only RIP-2 multicast packets and RIP-2
broadcast packets will be received. In this case, RIP-1 packets will be rejected.
