18.3.2.2.1 auto-summary
Command: auto-summary
no auto-summary
Function:
Configures route aggregation; the “
no auto-summary”
command disables route
aggregation.
Parameters:
N/A.
Default:
Auto route aggregation is not used by default.
Command mode:
RIP configuration mode
Usage Guide:
Route aggregation reduces the amount of routing information in the route table and
amount of information to be exchanged. RIP-I does not support subnet mask, forwarding subnet
route may result in ambiguity. For this reason, route aggregation is always enabled for RIP-I. If you
are using RIP-II, you can use “no auto-summary” command to disable route aggregation. If subnet
route needs to be broadcasted, route aggregation can also be disabled.
Example:
Setting the RIP version to RIP-II and disables route aggregation.
Switch(Config)#router rip
Switch(Config-Router-Rip)#version 2
Switch(Config-Router-Rip)#no auto-summary

18.3.2.2.2 default-metric
Command: default-metric
<
value
>
no default-metric
Function:
Sets the default route metric for route to be introduced; the “
no default-metric
”
command restores the default setting.
Parameters:
< value>
is the value of route metric, ranging from 1 to 16.
Default:
The default route metric is 1.
Command mode:
RIP configuration mode
Usage Guide:
“
default-metric
” command sets the default route metric used in introducing routes
from the other routing protocols to RIP. When using “
redistribute
” command to introduce routes of
the other protocols without specifying a detailed route metric, the default route metric set by
“
default-metric
” command applies.
Example:
Sets the default route metric for introducing routes of the other protocols into RIP to 3.
Switch(Config-router-rip)#default-metric 3
