your wrote below :

Require Peer SNI support requires that all network peers provide SNI support as well. If you enable both "Default SSL Profile for SNI" and "Require Peer SNI Support," the system terminates the connection when the client provides no SNI extension. The default for this setting is unchecked.

Could you explain what is SNI extension and how client provides it and how LTM detects it, moreover, if I want to use iRule for that, what is parameter name ?
