The following example provides the input required to configure the designated router topology as displayed in OSPF Designated Router Topology:
Router 1(rw)->configure Router 1(rw-config)->interface vlan 1 Router 1(rw-config-intf-vlan.0.1)->ipv6 ospf priority 25 Router 1(rw-config-intf-vlan.0.1)->exit Router 1(rw-config)->
Router 2(rw)->configure Router 2(rw-config)->interface vlan 1 Router 2(rw-config-intf-vlan.0.1)->ipv6 ospf priority 10 Router 2(rw-config-intf-vlan.0.1)->exit Router 2(rw-config)->
Router 3(rw)->configure Router 3(rw-config)->interface vlan 1 Router 3(rw-config-intf-vlan.0.1)->ipv6 ospf priority 30 Router 3(rw-config-intf-vlan.0.1)->exit Router 3(rw-config)->
Router 4(rw)->configure Router 4(rw-config)->interface vlan 1 Router 4(rw-config-intf-vlan.0.1)->ipv6 ospf priority 0 Router 4(rw-config-intf-vlan.0.1)->exit Router 4(rw-config)->
