Q. Explain TCP-IP Routing Architecture?
- The TCP/IP routing architecture looks extremely much like the OSI routing architecture.
- Hosts utilize a discovery protocol to obtain the identification of gateways and other hosts attached to the same network (sub network).
- Gateways within autonomous systems (routing domains) function an interior gateway protocol (intradomain IS-IS routing protocol) as well as between autonomous systems they operate exterior or border gateway protocols (interdomain routing protocols). The details are different however the principles are the same.
