VRF default: Update interval is set to 30 seconds.
VRF default: Route invalidation interval is set to 180 seconds.
VRF default: Route flush interval is set to 120 seconds.
In this instance, an interface with an IP address 10.71.0.2 is not running RIP. This interface is part of a network which was
disabled (10.71.0.0 for example).
RIP Passive Mode Operation
In order for an interface to receive and process RIP messages, but not advertise its routes, system administrators can
enable passive RIP mode operation. By the same token, this passive RIP mode of operation can be disabled.
The following RIP passive mode related enable and disable tasks, along with their associated commands are grouped for
convenience. This is not intended to be a step-by-step procedure.
Enabling RIP Passive Mode
To enable RIP passive mode on an interface, enter the following command:
configure router rip [vrf <name>] passive-interface {cable-mac <mac> | default | gigabitethernet
<slot>/<port> | tengigabitethernet <slot>/<port>}
Where:
cable-mac <mac>
is the MAC identifier
default
sets all RIP enabled interfaces to be passive
gigabitethernet <slot>/<port> |
tengigabitethernet <slot>/<port>
is the RCM slot number/port number of the specified
interface
Confirm that RIP is running in passive mode on an interface:
show ip rip
The output should look similar to the following:
RIP Interfaces
Interface VRF Df Met Auth Mode State
10.71.0.2 default 1 disabled passive
10.71.64.2 default 1 disabled disabled
