Configuration procedure
1) Create VLANs, and assign corresponding ports to the VLANs, and configure the IP address of
each VLAN interface as shown in Figure 12-5. The configuration procedure is omitted.
2) Configure Switch A
# Configure a static route to 30.1.1.0/24, with the address of the next hop as 10.1.1.2 and the default
priority 60. This static route is associated with track entry 1.
