11. Each time a capable device receives these packets, that device modifies the packet, incrementing the hop count by one. 12. RIP uses the hop count of the destination whereas IGRP takes into account other information such as node delay and available bandwidth. 13. As a sanity check you could put in a maximum hop count of say, twenty, just in case things go funny. 14. This is based on the observation that a 5-bit hop count ( 32 max hops ) is sufficient for almost all Internet routes. 15. The "'hop count "'refers to the number of intermediate devices through which data must pass between source and destination. 16. A hop count of " n " means that " n " gateways separate the source host from the destination host. 17. Routers are capable of managing hop counts , but other types of intermediate devices ( e . g . hubs and bridges ) are not. 18. If it finds a non-zero hop count it inserts its IP hash, sets the hop count to zero and forwards the packet on. 19. If it finds a non-zero hop count it inserts its IP hash, sets the hop count to zero and forwards the packet on. 20. In addition, the device compares the hop count against a time to live limit and discards the packet if its hop count is too high.
