The IR8140H supports IKEv2 dynamic routing from Cisco IOS-XE Release 17.8.1. The router can redistribute WPAN external routes (for example, Mapping of Address and Port-Translation Mode (MAP-T) routes) into IKEv2 and supports spoke and hub distribution.

The IR8140H will now support High Availability for WPAN between two routers (each with one WPAN module). WPAN HA uses HSRP to track state between the two routers. The WPAN state (RPL routes, mesh-security sessions and keys, multicast sequence numbers) is synchronized between the two routers using a reliable UDP based protocol.

Note	WPAN HA will not integrate with the rest of the IOS XE HA infrastructure. It is specific to WPAN. WPAN HA will only be supported between two IR8140 routers with a single WPAN interface each. This feature cannot be used together with the Dual WPAN interface feature.

Yang operational model support has been added for the information that is currently available through WPAN show commands. This includes commands for the following:

• The WPAN interface (for example, show wpan 0/X/0)

• RPL commands (for example, show wpan 0/X/0 rpl)

• meshsec (for example, show mesh-security)

The IR8140H supports third party modules from Cisco IOS-XE Release 17.8.1.

Before inserting the 3rd-party module, use the CLI hw-module subslot 0/1 3rdparty-mode to configure the slot as 3rd-party mode, to avoid delays during boot caused by the system looking for ACT2, which does not exist on a 3rd-party module.
