Preview Qmap: "Frame-relay Basis.qmap"


According to the topology above, there are 2 virtual circuits between R3, R4 and R5. Configure Frame-Relay on a subinterface of each router so that dynamic routing functions properly across any two devices.

[Chris]

There are two types of sub-interface: point-to-point and multipoint.

• Point-to-point sub-interface allows only 1 dlci configured via
  (config-if)#frame-relay interface-dlci DLCI-number
• Multipoint sub-interfaces, first disable inverse ARP via
  (config-if)#no frame-relay no inverse-arp

Then use "(config-if)#frame-relay map ip 11.11.11.4 304" to map the next-hop with the DLCI. Add broadcast parameter behind this command to support the transmission of broadcast and multicast packets.
