summary of networks

[carl_townshend]

Is it possible for me to summarize my networks 192.168.11.0, 192.168.12.0, 192.168.13.0 ? into 1 eigrp statement, can I advertise them as the 192.168.0.0 network ? would this advertise each class c network out though ?

yes, you could advertise 192.168.0.0/16 via eigrp.

this advertise all three networks you are talking of.

this could be manually summarized to 192.168.0.0/21

but would this not be advertising the /16 network ? I have other sites already on this !!

Hello Carl,

192.168.11.0, 192.168.12.0, 192.168.13.0

there's no way to aggregate these routes in a single stamement without including other subnets.

The best you can do is:

192.168.11.0/24

192.168.12.0/23

HTH,

if it does, remember to rate this post.

The best single aggregate you could use would be:

192.168.8.0/21

which would include the following range of addresses:

192.168.8.0 - 192.168.15.255

Let me know if this helps by rating the post.

But that would be too inclusive and could create routing issues, if 192.168.15.0/24 is on a different part of the network for instance.

Absolutely, but it is the only way I can see to meet the original requirement.
