Configuring SSO on a Cisco ASR 1001, Cisco ASR 1002, or Cisco ASR 1004 Router
The following instructions show how to configure SSO on a Cisco ASR 1001, Cisco ASR 1002, and
Cisco ASR 1004 Routers. The standby IOS process is created automatically as part of these
configuration steps.
Step 1
(Optional) Enter the
show version
command to confirm the amount of DRAM on your router:
Router#
show version
<some output removed for brevity>
32768K bytes of non-volatile configuration memory.
4194304K bytes of physical memory.
921599K bytes of eUSB flash at bootflash:.
39004543K bytes of SATA hard disk at bootflash:.
Configuration register is 0x2102
In the example
show version
output, the router has 4 GB of DRAM memory.
If you are using a Cisco ASR 1001, Cisco ASR 1002, or Cisco ASR 1004 Router with 2-GB DRAM
memory on the RP, SSO cannot be configured on your RP.
Step 2
(Optional) Enter
show redundancy states
to see the current HA configuration:
Router#
show redundancy states
my state = 13 -ACTIVE
peer state = 1 -DISABLED
Mode = Simplex
Unit ID = 6
Redundancy Mode (Operational) = Non-redundant
Redundancy Mode (Configured) = Non-redundant
Redundancy State = Non Redundant
In this example, HA for the dual RPs is not configured, as indicated by the nonredundant operational
mode.
Step 3
Enter
configure terminal
to enter global configuration mode:
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Step 4
Enter the
redundancy
command to enter redundancy configuration mode:
Router(config)#
redundancy
Router(config-red)#
Step 5
Enter
mode sso
to enable SSO, or
mode none
to disable dual software redundancy:
Router(config-red)#
mode sso
Router(config-red)#
mode none
Step 6
Return to privileged EXEC mode using any method, such as entering
Ctrl-Z
or the
exit
command
multiple times until you get to the # router prompt:
Router(config-red)#
^Z
Router#
