Hi everyone,
I just began to deep dive in some brand new ASR 1001.
I read about that functionnality and try to play with ... but unfortunatly it doesn't work.
- Hardware & Software Info:
IOS-XE Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.2(4)S2, RELEASE SOFTWARE (fc1)
IOS XE Version: 03.07.02.S
4 Gigabit Ethernet interfaces
32768K bytes of non-volatile configuration memory.
4194304K bytes of physical memory.
7741439K bytes of eUSB flash at bootflash:.
- EULA accepted
- extract of the "show feature license"
ASR1K# show license feature
Feature name Enforcement Evaluation Subscription Enabled RightToUse
adventerprise yes yes no yes yes
sw_redundancy yes yes no yes yes
- adventerprise image loaded at boot
- I enter the following command and obtain the following results:

As you can see when ASR reload, it always prompt us to save the config and boot again like it asked when i entered the mode sso command ... weird !
After login when i issue a "show platform" my RP is alone and active but no second process !
Is anyone has already configure that redundancy on ASR1001, the document contradict himself about that support ...
It says YES with some limitation and a paragraph below talk just about 1002 & 1004 platform ...
Thx for you help.

Hi Stephane,
Any good news in getting the dual ios up and running on the ASR-1001? I'm also interested in enabling the dual ios feature on our 1001's...
BR!

ASR1001 does not have the same architecture as ASR1002 and other ASR/1k
models. With ASR1001, RP, FP, CC are integrated and run on the same
Linux kernel. With ASR1002 and other models, RP/FP/CC have dedicated
CPU/Memory resource for each component.
What this means is that for SSO to be operational on ASR1001, we have
stated that you need to have 8GB. In other words, setting the redundancy
mode to none OR SSO in configuration does not matter when the node only
has 4GB DRAM. Regardless of what is configured, SSO will not be
operational when you have 4GB on a ASR/1001. This is documented at
