RIP (Routing Information Protocol) is a distance-vector routing protocol that uses hop count as its metric for path selection. RIP routers broadcast their entire routing table every 30 seconds as a broadcast. RIP is classified as a classful routing protocol, meaning it does not support the use of VLSM (Variable Length Subnet Masking) and requires all devices in a network to use the same subnet mask.

SNMP is the most widely used protocol for network monitoring
When a router receives a broadcast, it typically does not forward it to other networks, as routers are designed to separate broadcast domains. Instead, the router will usually drop the broadcast packet and may send an Internet Control Message Protocol (ICMP) message back to the sender if appropriate. This behavior helps to reduce unnecessary traffic and maintain network efficiency. In contrast, switches and hubs will forward broadcast packets to all devices within the same local network segment.
