OSPF shortcut

Filed under: IP Routing, ospf — ciscotips @ 5:58 pm

Many of the newbies get confused while configuring OSPF network statements. Wild card masks are sometimes a pain. Although I have already covered wild card masks usage in my earlier post. Here is an example in lieu to OSPF.

OSPF usage

router ospf process id
network x.x.x.x wildcardmask area area-id

interface serial0
ip address

To add serial0 in OSPF, command will be

router ospf 100 —-> 100 is a process id
network area 0

Here we have used wild card mask. but you know we can accomplish the same task with following:-

router ospf 100
network area 0

Here we are directly advertising interface address rather then network. This is a convenient method as you don't have to always worry abt wild card masks.
