Frame Relay Wred Configuration Example - 3Com MSR 50 Series Configuration Manual

Frame Relay WRED
Configuration Example
[RouterB] interface serial 2/0
[RouterB-Serial2/0] link-protocol fr
[RouterB-Serial2/0] ip address 10.1.1.1 255.0.0.0
[RouterB-Serial2/0] fr traffic-shaping
# Create DLCI 16.
[RouterB-Serial2/0] fr dlci 16
# Apply the Frame Relay class named test1 to DLCI 16.
[RouterB-fr-dlci-Serial1/0-16] fr-class test1
Network requirement
Router A and Router B are connected to the same Frame Relay network.
■
Establish WFQ queues on a FR PVC created Router A, scheduling the queues
■
using the WRED algorithm according to packet DSCP.
Reserve bandwidth for packets with specific DSCP values on a FR PVC created
■
on Router B and apply the WRED algorithm according to packet DSCP. For
other packets on Router B, use WFQ algorithm and apply corresponding WRED
policy.
