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
