Setup guide

interface (name) - Frame Relay interface
Notes
A DLCI is a channel number (Data Link Connection Identifier) which is attached to data frames to
tell the network how to route the data. Frame Relay is "statistically multiplexed", which means that
only one frame can be transmitted at a time but many logical connections can co-exist on a single
physical line. The DLCI allows the data to be logically tied to one of the connections so that once it
gets to the network, it knows where to send it.
Frame Relay Configuration
Example with Cyclades Interface
Let us consider the following network setup with Wandy router with Cyclades PC300 interface
connected to a leased line with baseband modems and a Cisco router at the other end.
[admin@Wandy] ip address> add interface=pvc1 address=1.1.1.1 netmask=255.255.255.0
[admin@Wandy] ip address> print
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0 1.1.1.1/24 1.1.1.0 1.1.1.255 pvc1
