Configuration procedure
1. Assign IP addresses and masks to interfaces (see Figure 29 )
Details not shown
2. Enable OSPF to advertise host routes with LSR IDs as destinations
Details not shown
After configuration, you can perform the display ip routing-table command on each router. You
can see that all nodes learnt the host routes of other nodes with LSR IDs as destinations.
3. Configure MPLS TE basic capabilities, and enable CSPF
