Q) Routing Protocols operate at which layer of OSI model?
A) Routing Protocols are used to select best path whenever router is having 2 or more paths to reach same destination. Routing Protocols work on different layers of OSI Model.
EIGRP------------- Network Layer
OSPF-------------- Network Layer
RIP---------------- Application Layer
BGP---------------- Application Layer
IS-IS--------------- Data Link Layer
Routing Protocols work on different different layers because of transportation of data used by them....
EIGRP uses IP Protocol number 88 (layer 3)
OSPF uses IP Protocol number 89 (layer 3)
RIP uses UDP protocol number 520 (layer 4)
BGP uses TCP protocol number 179 (layer 4)
