Static cellular interface IPv6 mode
When a PDN router interface is configured for static cellular interface IPv6 mode, consider the following points when setting up a service over a PDN router interface and its associated cellular port:
GRE-MPLS based services are not supported with static cellular interface IPv6 mode.
Services that are supported using IPSec secure interfaces are supported with static cellular interface IPv6 mode.
In a dual SIM deployment, the points listed above must be considered for each PDN router interface configured for each SIM.
