58 ESR Series Routers Operation Manual
Fig. 7.13—Network structure
Solution:
Pre-configure IP addresses on interfaces according to the network structure shown in Fig. 7.13.
Create OSPF process with identifier 10 and proceed to the OSPF protocol configuration mode:
esr(config)# router ospf 10
Create and enable the required area:
esr(config-ospf)# area 1.1.1.1
esr(config-ospf-area)# enable
esr(config-ospf-area)# exit
Enable announcement of the routing information from RIP:
esr(config-ospf)# redistribute rip
Enable OSPF process:
esr(config-ospf)# enable
esr(config-ospf)# exit
Neighbouring routers are connected to gi1/0/5 and gi1/0/15 interfaces. To establish the
neighbouring with other routers, map them to OSPF process and the area. Next, enable OSPF routing for
the interface.
esr(config)# interface gigabitethernet 1/0/5
esr(config-if-gi)# ip ospf instance 10
esr(config-if-gi)# ip ospf area 1.1.1.1
esr(config-if)# ip ospf
esr(config-if)# exit
esr(config)# interface gigabitethernet 1/0/15
esr(config-if-gi)# ip ospf instance 10
esr(config-if-gi)# ip ospf area 1.1.1.1
esr(config-if-gi)# ip ospf
esr(config-if-gi)# exit
esr(config)# exit
