IP Routing
In order to troubleshoot an IP Routing problem, a basic understanding of the IP protocol/feature is
required. Some basic concepts are covered below. Reading RFCs 791, 1812 and 1716 are highly recom-
mended to anyone implementing or troubleshooting IP Routing on their switch/network. IP Routing is a
process by which layer 3 packets are forwarded between two different subnets or networks.
Here is a list of the IP RFCs to review:
• RFC 791 (IP)
• RFC 1812 (Requirements for IP Version 4 Routers)
• RFC 1716 (Towards Requirements for IP Routers)
Here is a list of the RIP RFCs to review:
• RFC 1058 (RIP v1)
• RFC 2453 (RIP v2)
• RFC 1722 (RIP v2 Protocol Applicability Statement)
• RFC 1723 (RIP v2 Carrying Additional Information)
• RFC 1724 (RIP v2 MIB Extension)
Here is a list of the OSPF RFCs to review:
• RFC 2328 (OSPF Version 2)
• RFC 1403 (BGP OSPF Interaction)
• RFC 1587 (The OSPF NSSA Option)
• RFC 1765 (OSPF Database Overflow)
• RFC 2370 (The OSPF Opaque LSA Option)
• RFC 1745 (BGP4/IDRP for IP-OSPF Interaction)
• RFC 1586 (Guidelines for Running OSPF Over Frame Relay Networks)
• RFC 1370 (Applicability statement for OSPF)
• RFC 1850 (OSPF v2 MIB)
Reading the “Configuring IP” chapter in the appropriate OmniSwitch Network Configuration Guide is also
highly recommended.
