Mode Interface Configuration for a VLAN interface.
Usage notes Route summarization is a technique that helps network administrators reduce the
size of the routing tables by advertising a single super-network that covers a range
of subnets.
You statically configure an IP summary address on a router interface. The router
then advertises the summary address downstream through this interface. This
means that:
•
•
This command will be rejected if there is no IP address configured on the interface.
NOTE
running in RIPv1.
Example The subnets 10.4.1.0/24, 10.4.2.128/25 and 10.4.3.0/24 can be summarized and
advertised as 10.4.0.0/16 on vlan1 using the following commands:
awplus#
awplus(config)#
awplus(config-if)#

Parameter
<ip-address/prefix-length>
all the routers that are downstream from the configured interface will
receive only the summary route, and none of the child routes via the RIP
advertisement.
As long as at least one of the child routes is valid, the router will propagate
the summary route. But when the last child that is part of the summarized
range disappears, then the router will stop advertising the summary route
through the interface.
