ietf: Internet Engineering Task Force (IETF) standard encapsulation format
(default).
nonstandard: Nonstandard compatible encapsulation format.

frame relay.
By default, the link-layer protocol encapsulated on the interface is PPP.
The frame relay encapsulation can be either ietf or nonstandard. IETF
encapsulation conforms to RFC 1490, that is, it supports the IETF standard and is
compatible with dedicated encapsulation format of mainstream routers.
If you encapsulate a frame relay interface using any of the above frame relay
formats, the packets are encapsulated in the corresponding frame relay format
before they are forwarded through the interface. That is, two devices can
communicate with each other if the interfaces of both sides can recognize packets
in both of the formats even if they are encapsulated using different frame relay
formats. If an interface on one side cannot recognize packets of both formats, you
need to encapsulate the two interfaces using the same frame relay format.
# Configure frame relay encapsulation on interface Serial 2/0 and select the
nonstandard encapsulation compatible format.
