15.3.2.2.1 auto-summary
Command: auto-summary
no auto-summary
Function: Configure route aggregation; the “no auto-summary” command disables
route aggregation.
Parameter: N/A.
Default: Auto route aggregation is not used by default.
Command mode: RIP configuration mode
Usage Guide: Route aggregation reduces the amount of routing information in the route
table and amount of information to be exchanged. RIP-I does not support subnet mask,
forwarding subnet route may result in ambiguity. For this reason, route aggregation is
always enabled for RIP-I. If you are using RIP-II, you can use “no auto-summary”
command to disable route aggregation. If subnet route needs to be broadcasted, route
aggregation can also be disabled.
Example: Set the RIP version to RIP-II and disables route aggregation.
