Hi Luc André,

Thanks. Those updates look good. I’m still a little hazy about what the outcomes are in a scenario with mixed compliant and non-compliant PEs, but it’s clearer than it was. I’m sure I could work it out if I were an expert, it’s just that… I’m not.

About this one:

...
“advanced synch” you are correct, this is a francization – what is meant is ‘prior to failure’ i.e. “in advance”. I will update to better grammar.  Prior?

That is better, but I’m still left with some questions. The text from version 13:

   The Port-Active mode poses a challenge to synchronization since the
   "standby" port may be in a down state.  Transitioning a "standby"
   port to an up state and stabilizing the network requires time.  For
   Integrated Routing and Bridging (IRB) and Layer 3 services, prior
   synchronization of ARP / ND caches is recommended.  Additionally,
   associated VRF tables may need to be synchronized.  For Layer 2
   services, synchronization of MAC tables may be considered.

How, specifically, would I be expected to accomplish prior synchronization of ARP/ND caches, VRF tables, and MAC tables?

Thanks,

—John
