  1. Routing Information Protocol

  2. Contents • Routing • Background • Basic capabilities and features • RIP Packet Format • RIP 2

  3. Routing • Moving information across a network • Routing occurs at Layer 3 • Routing involves two basic activities: • Determining optimal routing paths • Transporting information groups

  4. Background • Routing protocol RIP defined in • Request For Comments (RFC) 1058 • Internet Standard (STD) • Uses distance vectors to identify the best path to any given destination address • RIP 2 defined 1994 in RFC 1723

  5. Basic capabilities and features of RIP • Routing update process • RIP routing metrics • Routing stability • Routing timers

  6. RIP Packet Format • IP RIP Packet Consists of Nine Fields • RIP 1 • RIP 2

  7. RIP 2 • Extension of RIP’s capabilities • RIP messages carry more information • Authentication mechanism to secure table updates • Supports subnet masks
