Routing Information Protocol (RIP) Configuration
157
Software Configuration Guide, Revision 1.03
summary
name
•
default
for RIP default routes,
•
host
for IP host routes,
•
self-as-default
for self as RIP default routes and
•
static
for static IP routes.
Depending on the RIP announcing method the last option for the command in step 3 must be
explicitly selected. It is possible to have more than one RIP announcing method enabled
concurrently.
Procedure
To enable RIP announcing on an interface

Example: Enabling RIP Announcing
The following example shows how to enable the RIP default routes and IP host routes RIP
announcing method on IP interface
wan
on a SmartNode.
SN(cfg)#
context ip router
SN(ctx-ip)[router]#
interface wan
SN(if-ip)[wan]#
rip announce default
SN(if-ip)[wan]#
rip announce host
18.11 Enabling RIP Auto Summarization
Summarizing routes in RIP Version 2 improves scalability and efficiency in large networks.
Auto-summarization attempts to automatically summarize groups of adjacent routes into single
entries, the goal being to reduce the total number of entries in the RIP routing table, reducing the size
of the table and allowing the router to handle more routes.
RIP auto-summarization (automatic network number summarization) is disabled by default. With
auto-summarization, the SmartNode summarizes sub prefixes to the Class A, Class B, and Class C
network boundary when class network boundaries are crossed.
