Usage Guidelines

Usage Scenario

To check information about sham links in an OSPF area, run the display ospf sham-link command. The command output helps with sham link troubleshooting.

Init: Hello packets are received from the neighbor. 2-Way: A Hello packet is received from the neighbor, and the neighbor list in the Hello packet contains the local router ID, indicating that the two ends can interwork. ExStart: First step in establishing the adjacency. The master and slave relationship and DD sequence number are negotiated. Exchange: The two sides begin to implement LSDB synchronization using DD, LSR, and LSU packets. Loading: LSDBs are being synchronized using LSR and LSU packets. Full: The LSDBs have been synchronized. Both sides set up the adjacency and they are in the Full state.
Cost	Cost of the sham link.
Neighbor ID	Neighbor ID.
