Looking at custom template to design a service involving ASA and CSR - with ASA doing ACLs and CSR for Site to Site IPSec VPN - supporting Ikev1 or ikve2 with myriad options. ASA has a interface/sub-interface for group of users and calls CSR with options to set the IPSec tunnel. Looking for any guidance on Variable naming - ? length - uniqueness - include the name of service chain or component of service chain - append it to the variables ? Any best practises to share ?
