Route Summarisation

Hi all,
Can anyone see a better way of doing this? Its been awhile...
Ideally I would like to summarise the following subnet as a single route:
10.60.20.0/24
10.60.30.0/24
10.60.40.0/24
10.60.50.0/24
10.60.10.0/24 is in use elsewhere so can't be included in the summarisation.
The best mask I can get is 255.255.192.0, but surely this is going to catch 10.60.10.0/24 as well?

Difficult to summarise because 10.60.10.0/24 cannot be summarised.
The only way I can see you achieving this: -
10.60.10.0/24
10.60.20.0/24
10.60.30.0/24
10.60.32.0/19 (summarises the last two routes, as the /19 will catch the .40 and .50)
The IP design itself does not lend for simple summarisation. -

mattrgee,
Other than the mask, is there anything else you need for a route summarization?
