Cisco Hoot and Holler over IP with Frame-Relay Topology (One Hoot Group)
Figure 6 Cisco Hoot and Holler over IP with Frame-Relay Topology
In this topology, three routers are connected using 64K Frame-Relay PVCs in a hub and spoke topology,
with Router 1 being the hub. We have defined one hoot and holler group. All three routers have been
configured to traffic-shape their data and voice on the WAN to CIR, and all three routers are using IP
RTP priority to guarantee QoS for the Cisco Hoot and Holler over IP packets. In addition, the
frame-relay broadcast-queue is disabled on the serial interfaces. This occurs because, by default, the
