Disable automatic route summary

The automatic route summary of the RIP is the process to automatically summarize them
into classful network routers when subnet routes pass through classful network borders. By
default, the RIPv2 will automatically perform route summary, while the RIPv1 does not
support this feature.
The automatic route summary function of the RIPv2 enhances the scalability and
effectiveness of the network. If there are any summarized 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 summarized routes than the separate routes. There are
the following factors:
In looking up the RIP database, the summarized routes will receive preferential

treatment;
In looking up the RIP database, any sub-routes will be ignored, thus reducing the

processing time.
Sometimes, you want to learn the specific sub-net routes, rather than only see the
summarized network routers, you should disable the automatic route summary function.
To configure automatic route summary, execute the following commands in the RIP routing
process mode:
Command
DGS-3610(config-router)# no auto-summary
DGS-3610(config-router)# auto-summary
After disabling the automatic summary, the interface-level summary can be configured.
Execute following commands to configure the address and sub-net route summary under
certain interface:
Command
DGS-3610(config-if)# ip summary-address rip
ip-address ip-network-mask
DGS-3610(config-if)# no ip summary-address
rip
ip-address ip-network-mask

Configuring RIP Authentication

The RIPv1 does not support authentication. If the device is configured with the RIPv2 routing
protocol, you can configure authentication at the appropriate interface.
