Figure 3-6 Configuration Example 4
Configure the following in the local FRX4000/6000:
RLP parameters (Chapter
which the protocols will run. Configure frame relay on the RLP containing the
port to the network, and configure SNA on the RLP containing the port to the
FEP.
If LLC2 is not already configured in the FRX4000/6000, configure it on the
same RLP. (Frame relay must be configured on each RLP that will use it, but
LLC2 is configured on one RLP only. Performance may be enhanced if both
protocols are on the same RLP, since this eliminates the need to communicate
via the bus in the FRX4000/6000.)
Virtual LAN ID

Physical SNA port
conversion point is also defined in this record, under SNA PU Parameters.
(These parameters act as both LLC2 Originated Host and Originated Interface
records.)
Terminated LLC2 Host
Note that the remote FRX4000/6000 must have an Originated LLC2 Host.
Terminated LLC2 Interface
point at the frame relay interface. Note that the remote FRX4000/6000 must
have an Originated LLC2 Interface.
SVC Subscriber
frame relay LLC2 Terminated Host to the SDLC port. Note that this record is
not required on the remote FRX4000/6000, because that device originates the
connection (i.e., it is not being called).
LAN IDs can be configured in two places:
LLC2 node defaults, to identify a virtual bridge that connects the LLC2 function
to LAN interfaces.
LLC2 frame relay interfaces using 802.5 Source Route Bridge format, to
identify the ring number used by a source-route bridge at the remote end. (This
ID is normally assigned by a system administrator.) Note that the LAN ID on an
