8 Frame relay configuration
Nortel Secure Router 8000 Series
Configuration -WAN Access
After you configure FR routes with the fr dlci-switch interface tunnel command, you add
two routes into the FR routing table of the router. The inbound interface and outbound
interface of one route are "tunnel" and "serial" respectively, while those of the other are
"serial" and "tunnel".
A PVC whose DLCI number is out-dlci is generated on the tunnel interface. The state of this
PVC determines the state of a route.
