ASR 1002

How can we provide Hardware Redundancy between 2 routers in ASR 1002?

If we have 2 routers, One act as a Active router and Second one act as a Standby router. If Active router fails then Standby router will become Active.
How is this possible on 2 ASR 1002 routers?

I dont think it is possible!

Unfortunately, there is no Hardware Redundancy in ASR 1002.

The ASR 1001, ASR 1002-f, ASR 1002 and ASR 1004 only support software HA (redundancy). The ASR 1006 and ASR 1013 only support hardware HA.

Thanks for the information Vinod.

Just like VRRP is there any method to configure Redundancy between two routers?

Please check the reply above. I mistakenly replied to my own post. 

Here the Software redundancy doesn't referes to something like VRRP or HSRP. For Cisco ASR 1002 and 1004 routers, Route Processor Redundancy and Stateful Switchover can be used to switch between IOS processes.

Hello Vinod

I need Hardware redundancy.

Unfortunately Hardware HA is not supported.

On the Cisco ASR 1000 Series Routers, IOS runs as one of many processes within the operating system. This is different than on traditional Cisco IOS, where all processes are run within Cisco IOS.

This architecture allows for software redundancy opportunities that are not available on other platforms that run Cisco IOS software. Specifically, a standby IOS process can be available on the same Route Processor as the active IOS process. This standby IOS process can be switched to in the event of an IOS failure, and can also be used to upgrade subpackage software in some scenarios as the standby IOS process in an ISSU upgrade.

Following Table shows Software Redundancy Overview:

Router
Support for Two IOS Processes on Same Route Processor
Support for a Second IOS Process on Standby Route Processor
Explanation

Cisco ASR 1001 Router1

Yes

N/A

The Cisco ASR 1001 Router only supports one RP, so dual IOS processes run on the lone RP.

Cisco ASR 1002 Router

Yes

N/A

The Cisco ASR 1002 Router only supports one RP, so dual IOS processes run on the lone RP.

Cisco ASR 1004 Router

Yes

N/A

The Cisco ASR 1004 Router only supports one RP, so dual IOS processes run on the lone RP.

Cisco ASR 1006 Router

No

Yes

The Cisco ASR 1006 Router supports a second Route Processor, so the second IOS process can only run on the standby Route Processor.
