What is good way to summarize network 1.1.1.178 and ?

[wfqk]

Hi What is good way to summarize network below？

1.1.1.178

1.1.1.179

1.1.1.180

1.1.1.181

Using 1.1.1.176/30 is not good as it covers 1.1.1.176, 1.1.1.177, 1.1.1.178 and 1.1.1.179

Can we use prefix-list?

Hi,

Are you looking for a summarization without affecting address other than what is mentioned?. If so, I think it is not possible with 1 entry. You may need the below 2:

1.1.1.178/31

1.1.1.180/31

You are right. It looks like it is no useful to use prefix-list ge le, right?

[Nagendra Kumar Nainar]
