Cisco ASR fail-over for multiple subinterfaces?

Hi All,

I'm setting up a network with 2 Cisco ASR's (2 for failover reasons).

I'm looking to find a way where I can have a primary and secondary router (configured with the exact same config), so if the primary goes down, the secondary takes over.

I've been looking into HSRP, however this looks like I will need to configure this on every sub-interface and use up a lot of IP address space.

Is there a better way to do this?
