Re: Active/Active ECMP

I think we are just making recomendations based on lessons learned the hard way.  For me, HSRP is never a preferred solution.  I will only used it if forced to by some crazy Layer 2 limitation being imposed on me.  You do you man!

Re: Active/Active ECMP

I was just trying to understand the question of why do I think the standby node would receive traffic.

Dynamic routing and HSRP "can" lead to a very bad day.

 

Here is some reading.  Old but relevant.  For me, HSRP = too much headache.  We need to move beyond these Layer 2 limitations.  We have the routing protocols, "we can rebuild him... we have the technology..."  HAHA!

Hope this helps.

Re: Active/Active ECMP

Read it. Labbed it. It works. But "routing" doesn't solve LAN side requirements for hosts all the time. Not every corporation is running nexus as their core, not every corporation is stacking or using VSS. "Routing" doesnt solve a gateway problem.
