HSRP on Sub-interfaces

[Nehru Becirovic]

I'm in the process of configuring HSRP across two ASR that connect to Nexus stack.

We have couple of VLAN's that need to pass across between the two and so far I have configured sub-interfaces on both ASR for each of the VLAN's with both sharing the same HSRP IP.  

My question is, is this the best practice for this setup and should I configure HSRP across each sub-interface or just on my native VLAN interface?

Not sure what you are asking here. 

You would configure HSRP on any interface where you need redundancy for end clients in a vlan so not sure where the native vlan comes into this. 

Perhaps you could clarify ?

Sorry for confusion, 

My main question was, is HSRP best solution or should I go with VRRP or GLBP?

As far as tracking, I'm tracking status of every sub-interface right now and was thinking for simplicity if I should just monitor line-protocol of physical interface?

[Jon Marshall]

Right, thanks for clarifying. 

If you want to spread the load between both routers then GLBP would be the one to choose, otherwise HSRP is fine and I can't see a reason to pick VRRP instead. 

Not sure what you are tracking ie. you don't usually track the interface(s) with HSRP configured, it is usually another interface on the L3 device you are tracking. 

Sorry to keep asking but again could you clarify what you are doing re. tracking.

No problem. 

I'm tracking MPLS interface for obvious reasons and also tracking status of each sub-interface.  So in case of one of them goes down I decrement the priority and have the 2nd router preempt. 

[Jon Marshall]

If any of the HSRP interface(s) go down then HSRP hellos will no longer be sent on that vlan from the HSRP active router so the other router would take over for that vlan anyway. 

So you only need to track the MPLS interface and make sure you have preempt enabled on both routers.
