For example, suppose contiguous subnets routes 10.1.1.0/24, 10.1.2.0/24, and 10.1.3.0/24 exist in the
routing table. You can create a summary route 10.1.0.0/16 on Ethernet 1/1 to advertise the summary
route instead of the more specific routes.
To configure a summary route:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RIP view.
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
N/A
3. Disable RIPv2 automatic route
summarization.
undo summary
By default, RIPv2 automatic route
summarization is enabled.
4. Return to system view. Quit N/A
5. Enter interface view.
interface interface-type

To disable RIP from receiving host routes:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RIP view.

view. The interface view setting takes precedence over the RIP view settings.
To disable an interface from advertising a default route, use the rip default-route no-originate command
on the interface.
To configure RIP to advertise a default route:
Step Command Remarks
