RIP version information Display the version information for RIP,
including the RIP version of sending (V1 for
RIP-I, V2 for RIP-II), RIP sending method

version of receiving (V1 for RIP-I, V2 for
RIP-II, V12 for both RIP-I and RIP-II).
15.3.4.2 RIP Troubleshooting Help
In configuring and using RIP, the RIP may fail to run properly due to reasons such as
physical connection failure or wrong configurations. The user should ensure the following:
Good condition of the physical connection.
All interface and link protocols are in the UP state (use “show interface status”
command).
Enable RIP (use “router rip” command) first, then configure RIP parameters in the
appropriate ports, such as use RIP-I or RIP-II.
Next, note the inherent nature of RIP: RIP layer3 switch send route table update
information to all its neighbor layer3 switches every 30 seconds, if information from
a certain layer3 switch is not received in 180 seconds, that switch is considered
failed or unreachable, the route of that switch will be kept in the route table for
another 120 seconds before deleting. As a result, if a RIP route is deleted, wait 300
seconds to ensure the entry to be removed from the route table.
15.4 OSPF
15.4.1 Introduction to OSPF
OSPF is short for Open Shortest Path First. It is an interior dynamic routing protocol
for autonomous system based on link-state. The protocol creates a link-state database by
exchanging link-state among layer3 switches, and then uses the Open Shortest Path First
