5.4 Frame Relay Setup
Configuring Frame Relay on a WANpro includes the mapping of IP addresses to DLCIs and
telling the router which virtual circuits are connected.

5.4.1 Encapsulation
The WANpro support IP over Frame Relay encapsulation describes in RFC 1490, which is the
method for carrying network interconnect traffic over a frame relay backbone. It also describes a
simple fragmentation procedure for carrying large frames over a frame relay network with a
smaller MTU.
5.4.2 DLCI
The carrier gives you a specific DLCI (Data Link Connection Identifier) for each PVC that is a
path number of a portion of the PVC (the DLCI changes for each hop through the network), not
the address of the destination. It is a logical identifier with local significance only. Identifiers can
range from 16 to 991.
5.4.3 LMI
The carrier also gives you the LMI (Local Management Interface) type, The LMI is a set of
enhancements to the basic Frame Relay specification. LMI includes support for keepalives, a
multicast mechanism, global addressing, and a status mechanism. Your WANpro support three
LMI standards:
ANSI T1.617 Annex D
,
CCITT Q.933a Annex A
and
LMI by Frame Relay Forum
