Bpdu Tunneling Configuration Examples; Bpdu Tunneling For Stp Configuration Example - H3C S3600V2 SERIES Layer 2-Lan Switching Configuration Manual

To configure destination multicast MAC address for BPDUs:
Step
1. Enter system view.
2. Configure the destination
multicast MAC address for
BPDUs.
NOTE:
For BPDUs to be recognized, the destination multicast MAC addresses configured for BPDU tunneling must
be the same on the edge devices on the service provider network.

BPDU tunneling for STP configuration example

Network requirements
As shown in
CE 1 and CE 2 are edges 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 are access ports and belong
•
to VLAN 2. All ports that interconnect service provider devices are trunk ports and allow packets of
any VLAN to pass through.
MSTP is enabled on User A's network.
•
After the configuration, CE 1 and CE 2 must implement consistent spanning tree calculation across the
service provider network, and the destination multicast MAC address carried in BPDUs must be
0x0100-0CCD-CDD0.
