Examples of changing per-interface settings

Suppose that VLAN 30 is multinetted, with two subnets in area 1 and one subnet in area 5:

vlan 30 
ip ospf 10.10.30.1 area 0.0.0.1
ip ospf 10.10.31.1 area 0.0.0.1
ip ospf 10.10.32.1 area 0.0.0.5
If you wanted to quickly reconfigure per-interface OSPF settings for VLAN 30, such as those listed below, you could use the commands shown in the following figure.
  • Assign a cost of "5" to the two subnets in area 1 and a cost of "10" to the subnet in area 5.

  • Assign a dead interval of 45 seconds to the subnets in area 1 and retain the default setting (40 seconds) for the subnet in area 5.
