Selecting the RIP Version
You can specify whether RIP sends Version 1 updates, Version 2 updates with no
aggregation of subnets, or Version 2 updates with subnet aggregation.
• In RIP Version 1 mode (the default), RIP generates Version 1 updates only,
using the broadcast address as specified in RFC 1058. RIP aggregates subnet
information.
• In RIP Version 2 mode, RIP generates Version 2 updates, using the multicast
address 224.0.0.9 as specified in the RIP Version 2 RFC, 1388. RIP does not
aggregate subnet information.
• In RIP Version 2 mode with aggregation, RIP generates RIP Version 2
updates, using the multicast address, and performs aggregation of subnets into
a natural network advertisement on interfaces belonging to another network.
In both Version 2 modes, RIP checks for a password on all received updates (see
“Authenticating the Password on a Version 2 Update” on page 6-19).
By default RIP sends Version 1 updates. You can use the BCC or Site Manager to
choose Version 2 with or without aggregation of subnet information.
Using the BCC
Navigate to a RIP interface-specific prompt and enter
version
version
version is
rip1 (default)

For example, the following command causes RIP to send Version 2 updates with
aggregation of subnets.

rip/2.2.2.2#
