Set the additional routing

Note:
The rip metricout command takes effect only on the RIP routes learnt by the router
and the RIP routes generated by the router itself, but not on any route imported to RIP
from other routing protocols.
II. Configure RIP route summarization
Route summarization means that different subnet routes in a natural network
segment can be summarized into one route with a natural mask for transmission to
another network segment. This function is used to reduce the routing traffic on the
network as well as to reduce the size of the routing table.
Route summarization does not work for RIP-1. RIP-2 supports route summarization.
When it is needed to advertise all subnet routes, you can disable the function for
RIP-2.
Follow these steps to configure RIP route summarization:
Enter system view
Enter RIP view
Enable RIP-2 automatic
route summarization
