Reenable the FastEthernet 0/0 interface on the R2 router.
Step 5.
R2(config-if)#
no shut

%SYS-5-CONFIGI: Configured from console by console
Reenable the FastEthernet 0/0 interface on the R1 router.
Step 6.
Notice that an adjacency is formed with the R2 router. It can take up to 40 seconds for the
R2 router to send a Hello packet:
R1(config-if)#
no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed
state to up
R1(config-if)# end

Use the
show ip ospf neighbor
command on the R1 router to view the OSPF neighbor
information for that router.
