Connections can be between any two devices in the family FRM/
SmartSwitch 1800/FRX. In an FRM, the primary and backup DLCIs
must be on the same RLP, or a PVC must be configured between the
DLCIs.
In Example 1, the primary link is between Node 1/RLP 1/Port 2/DLCI 16 and Node
2/RLP 0/Port 0/DLCI 18. The DLCIs should be configured as described below. (The
parameters are described later in this chapter.) Then if the primary link goes down, a
connection will automatically be established between Node 1/RLP 1/Port 0/DLCI 17
and Node 2/RLP 0/Port 4/DLCI 17.
On Node 1, configure the following (as well as other parameters necessary for oper-
ation—this section deals only with the frame relay backup function):

RLP Port: 2
