Configuration procedure
1. Configure PE 1:
# Configure the destination multicast MAC address for BPDUs as 0x0100-0CCD-CDD0.
<PE1> system-view
[PE1] bpdu-tunnel tunnel-dmac 0100-0ccd-cdd0
# Create VLAN 2 and assign GigabitEthernet 4/0/1 to VLAN 2.
[PE1] vlan 2
[PE1-vlan2] quit
[PE1] interface gigabitethernet 4/0/1
[PE1-GigabitEthernet4/0/1] port access vlan 2
# Disable STP on GigabitEthernet 4/0/1, and then enable BPDU tunneling for STP on it.
[PE1-GigabitEthernet4/0/1] stp disable
[PE1-GigabitEthernet4/0/1] bpdu-tunnel dot1q stp
2. Configure PE 2:
# Configure the destination multicast MAC address for BPDUs as 0x0100-0CCD-CDD0.
<PE2> system-view
[PE2] bpdu-tunnel tunnel-dmac 0100-0ccd-cdd0
# Create VLAN 2 and assign GigabitEthernet 4/0/2 to VLAN 2.
[PE2] vlan 2
[PE2-vlan2] quit
[PE2] interface gigabitethernet 4/0/2
[PE2-GigabitEthernet4/0/2] port access vlan 2
# Disable STP on GigabitEthernet 4/0/2, and then enable BPDU tunneling for STP on it.
[PE2-GigabitEthernet4/0/2] stp disable
[PE2-GigabitEthernet4/0/2] bpdu-tunnel dot1q stp
BPDU tunneling for PVST configuration example
Network requirements
As shown in Figure 59 :
• CE 1 and CE 2 are edge devices on the geographically dispersed network of User A. PE 1 and PE
2 are edge devices on the service provider network.
• All ports that connect service provider devices and customer devices and those that interconnect
service provider devices are trunk ports and allow packets from VLANs 2 and 3 to pass through.
• PVST is enabled for VLANs 2 and 3 on User A's network.
Configure BPDU tunneling for PVST, so that CE 1 and CE 2 implement consistent PVST calculation across
the service provider network, and the destination multicast MAC address carried in BPDUs is
0x0100-0CCD-CDD0.
