Dany,

I think, if you do the following summarization, you should be able to
squeeze the 6 routes into 4.

10.10.103.0/24
10.10.104.0/24 &
10.10.105.0/24 all going out through 10.10.13.1

When converting the third octet into binary we get the following:
0110 0111 - 103
0110 1000 - 104
0110 1001 - 105

Consider only last two and the difference is only in the last bit, and we
can summarize these 3 routes into two as:

10.10.103.0/24 - 10.10.13.1
and the summarised 2nd and third as:
10.10.104.0/23 - 10.10.13.1
By applying the same technique you can summarise the
10.10.101.0/24 &
10.10.102.0/24 into

10.10.100.0/22 - 10.10.13.2 and
10.10.106.0/24 - 10.10.13.2

Hope this helps.
RS
