Cisco ASR 9000 Series Routing Configuration Guide

PurposeCommand or Action
If you have disconnected subnets, use the no keyword to
disable automatic route summarization and permit software
to send subnet and host routing information across classful
network boundaries.
Note
(Optional) Adjusts RIP network timers.
timers basic update invalid holddown
flush
Step 4
To view the current and default timer values, view output
from the show rip command.
Note
Example:
RP/0/RSP0/CPU0:router(config-rip)#
timers basic 5 15 15 30
(Optional) Changes the interpacket delay for the RIP updates sent.
output-delay delay
Step 5
Example:
RP/0/RSP0/CPU0:router(config-rip)#
output-delay 10
Use this command if you have a high-end router sending at
high speed to a low-speed router that might not be able to
receive at that fast a rate.
Note
(Optional) Configures NSF on RIP routes after a RIP process shutdown
or restart.
nsf
Example:
RP/0/RSP0/CPU0:router(config-rip)# nsf
Step 6
(Optional) Defines the interfaces on which the RIP routing protocol
runs.
interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-rip)#
interface GigabitEthernet 0/1/0/0
Step 7
(Optional) Allows the networking device to accept route entries
received in update packets with a metric of zero (0). The received
route entry is set to a metric of one (1).
metric-zero-accept
Example:
RP/0/RSP0/CPU0:router(config-rip-if)#
metro-zero-accept
Step 8
(Optional) Disables the split horizon mechanism.split-horizon disable
Step 9
Example:
RP/0/RSP0/CPU0:router(config-rip-if)#
split-horizon disable
•
By default, split horizon is enabled.
•
In general, we do not recommend changing the state of the
default for the split-horizon command, unless you are certain
that your application requires a change to properly advertise
routes. If split horizon is disabled on a serial interface (and that
interface is attached to a packet-switched network), you must
disable split horizon for all networking devices in any relevant
multicast groups on that network.
