DES-7200 Configuration Guide Chapter 2 RIP
Configuration
2-4
To configure a port to send only the packets of a specific version, execute the
following commands in the interface configuration mode:
Command Function
DES-7200(config-if)# ip rip send version 1
Specify to send the packets of
only RIPv1
DES-7200(config-if)# ip rip send version 2
Send the packets of only RIPv2.
DES-7200(config-if)# ip rip send version 1 2
Send the packets of RIPv1 and
RIPv2.
To configure a port to receive only the packets of a specific version, execute the
following commands in the interface configuration mode:
Command Function
DES-7200(config-if)# ip rip receive version 1
Receive the packets of only
RIPv1.
DES-7200(config-if)# ip rip receive version 2
Receive the packets of only
RIPv2.
DES-7200(config-if)# ip rip receive version 1 2
Receive the packets of RIPv1
and RIPv2.
2.2.5 Configuring Route Aggregation
The automatic route aggregation of the RIP means that the routes of subnets are
automatically aggregated into the routes of a classful network when they pass
through the border of the classful network. By default, the RIPv2 will automatically
perform route aggregation, while the RIPv1 does not support this feature.
The automatic route aggregation function of the RIPv2 enhances the scalability
and effectiveness of the network. If there are any aggregated routes, the
sub-routes contained in them cannot be seen in the routing table. This greatly
reduces the size of the routing table.
It is more efficient to advertise the aggregated routes than the separated routes.
There are the following factors:
Aggregated routes will be handled first when you search the RIP database.
Any sub-routes will be ignored will you search the RIP database, and thus
reducing the processing time.
Sometimes, you want to learn the specific sub-net routes rather than only viewing
the aggregated routes. In this case,you should disable the automatic route
aggregation function.
To configure automatic route aggregation, execute the following commands in the
