Hey guys,

(Via GNS3) I am using the CBT nuggets CCNP ROUTE and am doing the Adv EIGRP and came across the ip address for configuration for lo1 10.1.1.0/24

Now, this is a network addy. So i keep getting error messages of a bad mask.


Im using the c2600,


Specifically:

R2(config-if)#ip address 10.1.1.0 255.255.255.0
Bad mask /24 for address 10.1.1.0


I have used the ip subnet-zero command and the ip classless command.

My question is, how did he get his router to have those IPs?

What do i need to do to configure my routers to match those?

Thanks in advance,

Dice

the reason is that you're trying to set an IP which is network IP.
You can use IPs from 1 to 254. You can't use IP 0 or 255 (network & broadcast IP). So try to set IP 10.1.1.1 instead 10.1.1.0

Thats the issue, i understand that, but the CCNP ROUTE CBT ADVANCED EIGRP nugget shows int lo1 with that such IP address for the network with a /24.

Did he have a typo or mistake because its for all the networks represented.

Thanks again!

If you have access to that, by all means review it because that is where my confusion lies.

Also, how would you set a network ip or do you not?

I also get an "Invalid input detected at marker for this command as it will not execute.

"int serial 0/0.1 multipoint"

The error is noted under the "m" on the multipoint command.

the addresses next to loopbacks in that videos describes the network address where each loopback belongs.

R3(config-if)#ip add 10.5.1.0 255.255.255.0
Bad mask /24 for address 10.5.1.0
 

We should configure an ip address to interface not network

 

R3(config-if)#ip add 10.5.1.1 255.255.255.0
