58.3.9 Prohibitting the Route summary
Under the default circumstance, the RIP-2 supports the automatic route summary, summarizing the RIP-2
Routes when crossing the boundary of the classified network. And the RIP-1 Automatic Route Gathering
Function is always activated.

Route Gathering is prohibited, when crossing the boundary of the classified network, the router will then send
the route information of the sub-net and the host. Under the router configuration mode, the following command
should be taken to prohibit the automatic gathering.
Command Purpose
no auto-summary
Prohibit the Automatic summary
