Configuring Frame Relay Services
2-32 117376-B Rev. 00
Figure 2-12 shows a router with an Ethernet interface, and two frame relay
interfaces. The frame relay interface to the frame relay network is a DTE (right
side of illustration). The frame relay interface to the FRAD is a DCE (left side).
The router delivers all IP frames inbound on DLCI 50 to the IP interface. It also
delivers all IP frames inbound on DLCI 30 to the IP interface. The router delivers
all other traffic inbound on DLCI 30 via the PVC pass through system to DLCI
20, which transmits the data to the FRAD. All data inbound on DLCI 20 is
delivered via the PVC pass through system to DLCI 30, which transmits the data
to the frame relay network.
PVC pass through works with both leased line and dial-on-demand interfaces. It
works with Bay Networks data compression, congestion control, and traffic
shaping. It does not work with data encryption, which requires a direct mode
PVC.
Frame Relay Dial Services
Frame relay works with Bay Networks dial-on-demand and dial backup services.
For information about and directions for configuring dial services see Configuring
Dial Services.
Configuring Synchronous Lines for Frame Relay
If you enable frame relay on a circuit, Site Manager automatically sets the
following synchronous line parameters (T
able 2-5):
For more information on these parameters, refer to Configuring WAN Line
Services.
