IoT SDK IPSP roles

Question

Since the IoT SDK is not support the IPSP Router role.
Is that mean the nRF51822 can't been used by other MCU which is running Contiki to become a Edge Router?

This is a matter of software support, not nRF51822 hardware support.The IPSP and 6LoWPAN libraries in the IoT SDK only supports node role. The IoT SoftDevice supports Connection Oriented Channels with the Credit Based Flow Control Mode, which is needed for transport of IP packets. This SoftDevice can take a GAP peripheral role. 
 For router role you would need a SoftDevice that supports Connection Oriented Channels with the Credit Based Flow Control Mode and that can take a GAP central role. The S120 doesn't support Connection Oriented Channels with the Credit Based Flow Control Mode. 
 In addition the IPSP and 6LoWPAN libraries would need support for router role, which they don't.
