GTM persistence works different from LTM pools;

 

see following:

 

Persistence TTL: Persistence TTL specifies, in seconds, the length of time for which the persistence entry is valid. The default is 3600.

 

Drain Persistent Requests

 

Drain Persistent Requests is an additional global configuration that affects persistence behavior for all wide IPs with persistence enabled. Enabled by default, this setting is specifies that when you disable a pool or data center, load-balanced persistent requests will continue until the time-to-live (TTL) interval expires.
