Extended CCC version (
allows you to dedicate DLCIs 1 through 1022 to CCC. The logical interface
must have frame-relay-ccc
type, you can configure the
Extended TCC version (
Relay CCC, this encapsulation type allows you to dedicate DLCIs
1 through 1022 to TCC, which is used for circuits with different media on
either side of the connection.
Port CCC version (
Task Force (IETF) document, Frame Relay Encapsulation over Pseudo-Wires
(expired December 2002). This encapsulation type allows you to transparently
carry all the DLCIs between two customer edge (CE) routers without explicitly
configuring each DLCI on the two provider edge (PE) routers with Frame
Relay transport. The connection between the two CE routers can be either
user-to-network interface (UNI) or network-to-network interface (NNI); this
is completely transparent to the PE routers. The logical interface does not
require an encapsulation statement. When you use this encapsulation type,
you can configure the
Frame Relay Ether Type (
Frame Relay ether type encapsulation for compatibility with Cisco Frame Relay.
IETF frame relay encapsulation identifies the payload format using NLPID and
SNAP formats. Cisco-compatible Frame Relay encapsulation uses the Ethernet
type to identify the type of payload. Two related versions are supported:
TCC version (
frame-relay-ether-type-tcc
DLCIs 0 through 511. DLCIs 512 through 1022 are dedicated to TCC. This
encapsulation is used for circuits with different media on either side of the
connection.
Extended TCC version (
allows you to dedicate Cisco-compatible Frame Relay TCC for DLCIs 1 through
1022. This encapsulation is used for circuits with different media on either
side of the connection. Extended Frame Relay ether type TCC encapsulation
is supported on the same PICs as extended Frame Relay TCC encapsulation.
NOTE: When the encapsulation type is set to Cisco-compatible Frame Relay
encapsulation, ensure that the LMI type is set to ANSI or Q933-A.
Support for extended Frame Relay and flexible Frame Relay differs by PIC type, as
shown in Table 33 on page 381.
