2.7.2 Configuring RIP-2 Route Summarization

Route summarization is enabled in RIP-1 by default, and no need to be configured. RIP-2
supports VLSM and CIDR. You can configure route summarization in RIP-2 to improve the
flexibility of RIP-2. To broadcast all subnet routes, you can disable route summarization in
RIP-2.
Context
Route summarization indicates that multiple subnet routes on the same natural network segment
are summarized into one route with the natural mask when being advertised to other network
segments. Therefore, route summarization reduces the network traffic and the size of the routing
table.
Route summarization does not take effect in RIP-1. RIP-2 supports Variable Length Subnet
Mask (VLSM) and Classless Interdomain Routing (CIDR). To broadcast all subnet routes, you
can disable automatic route summarization of RIP-2.
Do as follows on the RIP switch:

RIP-2 route summarization
RIP-2 authentication mode
Configuring the link layer protocol
Configuring IP addresses for interfaces to ensure that neighboring nodes are reachable at
the network layer
Data
RIP-2 process ID
Network segment where the RIP-2 interface resides
NOTE
Route summarization is invalid when poison reverse is configured. When the summarized routes are sent
outside the natural network boundary, poison reverse in related views needs to be disabled.
