Ben Maddison taught me another aggregation trick:

	route-set:      AS37271:RS-EXAMPLE
	mp-members:     192.0.2.0/27
	mp-members:     192.0.2.32/27
	mp-members:     192.0.2.64/27
	mp-members:     192.0.2.96/27
	mp-members:     192.0.2.128/26
	mp-members:     192.0.2.128/27
	mp-members:     192.0.2.160/27
	mp-members:     192.0.2.192/27
	mp-members:     192.0.2.224/27
	descr:          Example route-set

BGPQ4 produces the following:

	$ bgpq4 -A AS37271:RS-EXAMPLE
	no ip prefix-list NN
	ip prefix-list NN permit 192.0.2.0/25 ge 27 le 27
	ip prefix-list NN permit 192.0.2.128/26 le 27
	ip prefix-list NN permit 192.0.2.192/26 ge 27 le 27

But the following aggregation also is valid, and shorter:

	ip prefix-list NN permit 192.0.2.0/24 ge 27 le 27
	ip prefix-list NN permit 192.0.2.128/26
