OSPF question

satishtech

Is the command ?
area 1 range 193.168.1.0 255.255.255.0

part of ccent or ccna ?
I am seeing it in the cisco command guide
under route summarization

You should check out the exam objectives.

The CCENT only covers single Area OSPF (area ZER0).

The ICDN2 talks about multi-area OSPF networks.

So... i would guess.... the latter :]

Example:

#config t
config#router ospf 1
router#network 192.168.1.0 0.0.0.255 area 1

Explanation:


#config t
config#router ospf [insert any number] - (the number doesn't need to follow across routers/L3's, but it's a good practice to label them accordingly) ie: 'router ospf 1'
router#network 192.168.1.0 0.0.0.255 area 1 - the last octet that has addressees is the determining factor for your wildcard mask. a good math for calculating a wildcard mask is 255.255.255.255 minus the custom mask, in this case it's a normal /24 so it would be 255.255.255.255 minus 255.255.255.0 which gives us the 0.0.0.255 as the wildcard mask. The rest is self-explanatory.

Also either assign a router-id or enable interface loopback 0 with an ip address so that OSPF has a router ID for the router. Those are done as such:

by default cisco will look to a loopback 1st in a router-ID selection, but most people just hardcode a router-ID.

router#router-id 1.1.1.1

or

#config t
config#inter l0
#ip add [insert address] [subnet mask] - since it's a loopback you can use a /32 mask since it's just one IP, so that would be a 255.255.255.255.


hope this help brother.

This command is only for route summarization, and I don't believe route summarization is included in the CCNA objectives at all, for any routing protocol. With that being said, the safest thing to do is check Ciscos website for the CCNA exam objectives as Networker already suggested.

Route summarization wasn't in my CCENT studies and I just finished my OSPF studies for CCNA with no talk about it in Odom's book. The only mention I've heard of it was in the CBTNuggets videos and Jeremy Cioara said pretty surely that it was a CCNP topic.
