Web14 Jun 2024 · The hop count is the number of devices that can be traversed in a route. A directly connected network has a metric of zero; an unreachable network has a metric of 16. This limited metric range makes RIP unsuitable for large networks. Information About Routing Information Protocol RIP Overview Web17 Nov 2024 · Uses UDP port 520. Classless protocol (support for CIDR). Supports VLSMs. Metric is router hop count. Maximum hop count is 15; infinite (unreachable) routes have a metric of 16. Periodic route updates sent every 30 seconds to multicast address 224.0.0.9. 25 routes per RIP message (24 if you use authentication). Supports authentication.

Web6 Jul 2024 · Time to live, best known as TTL or Hop Limit, is a mechanism that limits the lifespan or lifetime of data in a computer or network. TTL may be implemented as a counter or timestamp attached to or embedded in the data. Once the prescribed event count or timespan has elapsed, data is discarded or revalidated. In computer networking, TTL … WebHop Count Filtering (HCF): Hop Count (HC) is defined as the number of hops a packet traverses as it moves from the sender to the receiver [21]. HC is not usually sent in the IP packet but is rather inferred from the IP Time-to-Live (TTL) Field. The main function of IP TTL field is to prevent packets from looping forever.
