Procedure
Step 1 Configure an IP address for each interface and configure OSPF on all LSRs.
Configure the IP address and mask of each interface as shown in
interfaces.
Configure OSPF on all LSRs and advertise the host route of the loopback interface on each LSR.
The detailed configuration is omitted here.
After the configuration is complete, the LSRs can ping each other's LSR ID (loopback interface
address). Run the display ip routing-table command to view the routing table on each LSR.
