Config Sync Problem - LTM v11.1.0 Hotfix 1953.0

This has been confirmed as a bug in the LTM 11.1 bug id 378505 but fortunately there is a workaround

 

 

Add the two /etc/hosts entries to the Standby

 

tmsh modify sys global-settings remote-host add { yourhostname1 {addr yourprivateselfipforhost1 hostname yourhostname1}}

 

tmsh modify sys global-settings remote-host add { yourhostname2 {addr yourprivateselfipforhost2 hostname yourhostname2}}

 

 

Push this minor config update to the Active

 

tmsh run cm config-sync to-group yourdevicegroup

 

 

Save the config state on the Active and Standby units

 

tmsh save sys config partitions all

 

 

I can confirm that this workaround worked for me
