GTM HA / Config synch

Guys,   RE GTM synchronization groups and GTM High Availability (HA) (Ver 11.x)   What explicitly is synchronised configuration wise in a GTM synchronization group ? Is this only the bigip_gtm....

Cheers am better placed RE understanding (non) failover ;-) … ... But am miles from understanding GTM listeners reason being I have found no documentation on listeners / configuring listeners in ver 11.x ; all I have is snippets from ver 10.x and older DEVCENTRAL posts and a cursory overview in the GTM concepts doco. Suggestion I have from the links I have found is that this is under Global Traffic -> Listeners and has to be a (presumably local?) self IP. Other than the post above I have nothing suggesting these are LTM hosted IPs … Are we saying that DNS REQs hit an LTM ??? Presumably not ...

 

Can we get ver 11 documentation on how to configure listeners and hopefully through this a functional understanding may flow ?

 

Also there seems to be contradictory information as to ARP and listeners ... how does ARP work in this context.

    A GTM listener is just a funny name for an ltm virtual server listening on udp/53 (or tcp/53) with a DNS profile attached to it.
