Step 2 Configure static routes on devices to ensure network connectivity.
# On LSRA, configure two static routes with different priorities to LSRD, and on LSRD,
configure two static routes with different priorities to LSRA.
# Configure LSRA.
[LSRA] ip route-static 2.2.2.2 32 gigabitethernet 1/0/0
[LSRA] ip route-static 3.3.3.3 32 gigabitethernet 2/0/0
[LSRA] ip route-static 30.1.1.1 30 gigabitethernet 1/0/0
[LSRA] ip route-static 40.1.1.1 30 gigabitethernet 2/0/0
[LSRA] ip route-static 4.4.4.4 32 gigabitethernet 1/0/0 preference 40
[LSRA] ip route-static 4.4.4.4 32 gigabitethernet 2/0/0 preference 60
# Configure LSRB.
[LSRB] ip route-static 1.1.1.1 32 gigabitethernet 1/0/0
[LSRB] ip route-static 4.4.4.4 32 gigabitethernet 2/0/0
# Configure LSRC.
[LSRC] ip route-static 1.1.1.1 32 gigabitethernet 1/0/0
[LSRC] ip route-static 4.4.4.4 32 gigabitethernet 2/0/0
# Configure LSRD.
[LSRD] ip route-static 2.2.2.2 32 gigabitethernet 1/0/0
[LSRD] ip route-static 3.3.3.3 32 gigabitethernet 2/0/0
[LSRD] ip route-static 10.1.1.2 30 gigabitethernet 1/0/0
[LSRD] ip route-static 20.1.1.2 30 gigabitethernet 2/0/0
[LSRD] ip route-static 1.1.1.1 32 gigabitethernet 1/0/0 preference 40
[LSRD] ip route-static 1.1.1.1 32 gigabitethernet 2/0/0 preference 60
# After the preceding configurations, run the display ip routing-table protocol static command
on each LSR. The command output shows the configured static routes. In the following example,
the display on LSRA is used.
