Configuration procedure
1) Assign IP addresses and masks to interfaces (see
Omitted
2) Configure the IGP protocol
# Enable IS-IS to advertise host routes with LSR IDs as destinations on each node. (Omitted)
Perform the display ip routing-table command on each switch. You should see that all nodes learnt
the host routes of other nodes with LSR IDs as destinations.
3) Configure MPLS TE basic capabilities, and enable RSVP-TE and CSPF
# Configure Switch A.
