This topic explains HER redundancy, focusing on the configuration steps required at both the FND and HER (ASR) to ensure dynamic Flex VPN connectivity in an IoT FND solution.
-
HER redundancy requires configuration at both the FND and HER (ASR).
-
Flex VPN configuration at HER is performed once during initial setup and does not require modification for subsequent FAR additions.
-
The virtual tunnel template Flex VPN configuration at HER enables dynamic Flex VPN between HER (hub) and FAR (spoke).
Configuration details for HER redundancy
Configuration for HER redundancy involves two main components: FND and HER (ASR).
-
Configuration at HER (ASR). Flex VPN configuration at HER must be done once manually when setting up the IoT FND solution. After this, for subsequent addition of FARs, modification is not required at HER. This is because the virtual tunnel template Flex VPN configuration at HER manages dynamic Flex VPN between HER (hub) and FAR (spoke).
