D-Link DI-1750 Reference Manual page 274

Following example denies route whose prefix length larger than 25 in net 192/8:
ip prefix-list abc deny 192.0.0.0/8 ge 25
Following example allows route whose prefix length larger than 8 and less than 24 in the whole address
space:
ip prefix-list abc permit 0.0.0.0/0 ge 8 le 24
Following example denies route whose prefix length larger than 25 in the whole address space:
ip prefix-list abc deny 0.0.0.0/0 ge 25
Following example denies all routes of net 10/8. If the mask of A-class net 10.0.0.0/8 is less than or
equal to 32 bits, it will deny all routes:
ip prefix-list abc deny 10.0.0.0/8 le 32
Following example denies route whose mask length larger than 25 in net 204.70.1/24:
ip prefix-list abc deny 204.70.1.0/24 ge 25
Following example allows all routes:
ip prefix-list abc permit any
6. BGP Aggregate Route Examples
The following examples show how you can use aggregate routes in BGP either by redistributing an
aggregate route into BGP or by using the conditional aggregate routing feature.
In the following example, the redistribute static command is used to redistribute aggregate route
193.*.*.*:
ip route 193.0.0.0 255.0.0.0 null 0
!
router bgp 100
redistribute static
The following configuration creates an aggregate entry in the BGP routing table when there is at least
one specific route that falls into the specified range. The aggregate route will be advertised as coming
from your autonomous system and has the atomic aggregate attribute set to show that information
might be missing.
router bgp 100
aggregate 193.0.0.0/8
The following example not only creates the aggregate route for 193.*.*.*, but will also suppress
advertisements of more specific routes to all neighbors:
router bgp 100
aggregate 193.0.0.0/8 summary-only
7. Examples of BGP Route Reflector Configuration
The following is an example of route reflector. RTA, RTB, RTC and RTE belong to the same
Autonomous System AS200. RTA acts as route reflector. RTB and RTC are route reflector clients. RTE
