■ RIP view
Description Route aggregation can be performed to reduce the routing traffic on the network as
well as to reduce the size of the routing table. If RIP-2 is used, route summarization
function can be disabled with the undo summary command, when it is necessary to
broadcast the subnet route.
RIP-1 does not support subnet mask. Forwarding subnet route may cause ambiguity.
Therefore, RIP-1 uses route summarization all the time. The undo summary
command is invalid for RIP-1.
