Network requirements
As shown in
Device D work at the access layer.
Configure DRNI on Device A and Device B. In the DR system, Device A is the primary DR device,
and Device B is the secondary DR device.
Configure PVST on the devices to meet the following requirements:
•
Frames of a VLAN are forwarded along the spanning trees of the VLAN.
•
VLAN 10, VLAN 20, and VLAN 30 are terminated on the distribution layer devices.
•
The root bridge of VLAN 10, VLAN 20, and VLAN 30 is the DR system formed by Device A and
Device B.
