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)#
