Loopback and management Network

[tahalotfi]

Hi,

I am trying to create one loopback interface on each network devices in our LAN. For example 192.168.50.1/32 for one device, 192.168.50.2/32 for another device and so on. These ip addresses will be used for management purposes. So the 192.168.50.0/24 will be the management subnet. I am not sure that this is a right approach.

And if the answer is yes, then how can I have proper routing for them to be accessible from all over the network?

Thanks,

Taha

Well.....

If you go with the single network statement of 192.168.0.0 (which, by the way, I failed to mention earlier....you may need to include a mask with that statement), so it would look like this.......

network 192.168.0.0 255.255.0.0

due to the fact that without a mask, EIGRP sees this as a Class C network, and assumes a default mask of 255.255.255.0, which would break your EIGRP.

Using the single statement would eliminate the cons of advertising specific P2P links, which are really simply adding more routes to your routing table. However, in a smaller network, that's not necessarily an issue.

Please be sure to mark this issue as resolved if appropriate. :)

Thanks very much for your help. I think in your previous post:

"network 192.168.0.0 255.255.0.0 "

should be:

"network 192.168.0.0 0.0.255.255"

I believe I have seen it both ways, with the standard mask or wildcard mask; this may be determined by the IOS version, but I'm not sure.
