The following are the routing protocols:- IS-IS runs over the data link layer- OSPF, IGRP, and EIGRP run directly over IP; OSPF and EIGRP have their own reliable transmission mechanism while IGRP assumed an unreliable transport- RIP runs over UDP- BGP runs over TCPThanks.

We can create multiple Vlans even in layer 2 switch environment eg we make 4 Vlans in a 24 ports switch it will give us 8 port per Vlan .This will give us 4 broadcast domains.So less broadcast traffic is used.Secondly why use HUB? use switches as a 24 port switch is 24 collision domain.Thanks

there should be a smaller collision domain to have a efficient network. to create a smaller collision domain we can use sub-netting of ip's address. to make network more efficient we can use routers/...

Both RARP and IARP belong to Datalink layer protocols.RARP is used to get the IP address of specific host with the known MAC address.Inverse Arp(IARP) is used to get the IP address of remote host with the known DLCI number rather than MAC address, while configuring Frame relays.
