What is debug ip OSPF?
What is debug ip OSPF?
Displays information about OSPF adjacencies and authentication, including designated router (DR) and backup designated router (BDR) elections, sent and received hello packets, neighbor state transitions, and database description information.
How do I debug OSPF?
To display information about each OSPF packet that is received, use the debug ip ospf packet privileged EXEC command. The no form of this command disables the debugging output. The debug ip ospf packet command produces one set of information for each packet that is received.
What does debug ip packet do?
The debug ip packet command is useful for analyzing the messages traveling between the local and remote hosts. IP debugging information includes packets received, generated, and forwarded. This information is also sent to the sending host when the router configuration allows it.
Does OSPF process clear ip?
If the pid option is not specified, all OSPF processes are cleared. The following example clears all OSPF processes: clear ip ospf process.
What causes OSPF to flap?
A fault on an optical fiber or optical module causes frequent Up/Down state changes on the link between the devices. The unstable link results in OSPF neighbor relationship flapping.
What is debug IP ICMP?
debug ip icmp. This command displays information about Internal Control Message Protocol (ICMP) transactions and allows you to monitor the ICMP messages sent and received by your router. Each ICMP message has a source, destination, type, and code number.
What is point to OSPF?
A point-to-point connection is a serial link that connects two routers, making them Open Shortest Path First (OSPF) neighbors. Point-to-point connections are supported for i5/OS in an OSPF environment.
How do I stop debug PPP negotiations?
Use the debug ppp command to display information about the operation of PPP. Table 3-8 shows the command syntax. Use the no form of this command to disable debugging output.
How do I stop debug ripping?
Use the debug ip rip command to display information on Routing Information Protocol (RIP) routing transactions. The no form of this command disables debugging output.
How do I find OSPF priority IP?
You can verify which neighbors are the DR/BDR/DROTHER by using the show ip ospf neighbor command in privileged mode. Configures an OSPF priority on a per interface basis used to manipulate the DR/BDR election process.
