GRE Tunnel

Hi , I would like to calrify a basic query which may be very simple .

 

If i have an AP - dual band dual radio . It is associated VAP which is broadcasting a single ssid with only a vlan . for example vlan 1. How many GRE tunnel will it form with controller?

 

I am in assumption as it will have two BSSID as it has radio. Two GRE tunnel each one for a BSSID . Is my understanding correct?

Re: GRE Tunnel

If there two VAP with dual-band AP, so how many GRE tunnel will be contruct?  2 ? or 5?. 

 

my assumption is 5 GRE tunnel:

        2 ssid + 2 radio + 1 keepalive = 5 , is this correct?

 

any idea...

Re: GRE Tunnel

With AOS 6 or AOS 8 standalone, AOS 6 or 8 with HA, or with AOS 8 with the APs terminated on a cluster?

Re: GRE Tunnel

Since 6.1 documentation was mentioned, I will answer relating to that.

 

There is a GRE per SSID per radio, along with a GRE for that AP heartbeat. If you have the 2nd Ethernet port enabled on your AP, then there is an additional GRE for the Ethernet port traffic.

 

I hope this helps,
