2.
The previous information is printed by the debug ip ospf packet hello
command.

The interface addresses of the point-to-multipoint, NBMA, broadcast
network mode, and directly-connected route switching devices must
be configured in the same network segment. The masks must be the
same too. Otherwise, error may occur.
RIP Troubleshooting
Basic Idea of RIP Troubleshooting
Step 1: Collect the detailed network topology information. The dynamic
routing protocol is running between the route switching devices. After the
fault occurs, you should locate the fault, for example, locate the faulty
area or locate the specific devices.
Step 2: Check whether the routing devices are connected. The dynamic
routing protocol is running over the IP layer. To exchange routing protocol
packets between routing devices, the link layers must be connected.
Step 3: Locate the faulty routing switching device. On the routing
switching device, use the show tool to check the relevant information, for
example, RIP interface table and routing table.
Step 4: Through the collected information, you can generally locate the
fault. Then, use the debug tool provided by the system to analyze the
packet interaction to find out the cause of the fault.
Tools for Removing RIP Fault
s
Maipu switch provides many tools for finding RIP faults. The show tools
and the debug tools are as follows.
S h o w T o o l s
Show ip route rip
To quickly display the paths learned through RIP and added to the core
routing table.
Interface
To check the interfaces where RIP is enabled.
Show ip rip
Database
To check the RIP database information, including
timer, direct connected routes, learned route, and
redistributed route.
