The two main Frame Relay encapsulation types are indeed Cisco and IETF.

Cisco encapsulation is a proprietary format developed by Cisco Systems used to encapsulate the data packets within a Frame Relay frame. This encapsulation method provides certain features specific to Cisco devices, including support for certain types of network performance monitoring and management.

IETF encapsulation, on the other hand, adheres to the standards set by the Internet Engineering Task Force. This provides a more vendor-neutral approach that is widely compatible across different equipment from various manufacturers.

Understanding these encapsulation methods is crucial for network professionals, as they affect how data is transmitted over Frame Relay networks and ensure proper communication between devices of different vendors.
