Troubleshooting Dial-on-Demand Routing Issues in OSPF

‚  < ‚  Free Open Study ‚  > ‚  

This section discusses the issues related to DDR. When OSPF is configured over a DDR link, be sure to suppress OSPF Hellos because OSPF sends Hellos over point-to-point links every 10 seconds.

The most common issues related to OSPF over DDR links are as follows :

  • Problem: OSPF Hellos are bringing up the link

  • Problem: OSPF Hellos are not getting across the link*

  • Problem: Demand circuit keeps bringing up the link

NOTE

*The problem of OSPF Hellos not getting across the link was addressed earlier in the section "Troubleshooting OSPF Neighbor Relationships." Refer to this section for the solution to this problem.
