Important Considerations

Route aggregation mode determines which route table entries are
sent during a RIP Version 2 update.

If route aggregation mode is

enabled

, RIP-2 can function like RIP-1

and “collapse” route table entries for all subnets of a directly
connected network. For example, if route aggregation is

enabled

,

and the system is advertising subnets 150.100.31.0 and
150.100.32.0, only the entry for network 150.100.0.0 is sent in
the update. With RIP Version 2, you must enable route aggregation
mode if you want the interface to collapse the route table entries
and function like RIP-1.

If route aggregation mode is

disabled

(the default), a RIP-2

update sends all routing table entries.
