Configuring Destination Multicast Mac Address For Bpdus; Bpdu Tunneling Configuration Example - H3C SR8800 Configuration Manual

Configuring destination multicast MAC address for BPDUs

By default, the destination multicast MAC address for BPDUs is 0x010F-E200-0003. You can change it
to 0x0100-0CCD-CDD0, 0x0100-0CCD-CDD1 or 0x0100-0CCD-CDD2 through the following
configuration.
To configure the 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 BPDUs must be the
same on the edge routers on the service provider network.

BPDU tunneling configuration example

Network requirements
As shown in
• CE 1 and CE 2 are edges routers on the geographically dispersed network of User A; PE 1 and PE
2 are edge routers on the service provider network.
All ports that connect service provider and customer routers are access ports and belong to VLAN
•
2; all ports that connect service provider routers are trunk ports and allow packets of any VLAN to
pass through.
MSTP is enabled on User A network.
•
Configure BPDU tunneling, so that CE 1 and CE 2 implement consistent spanning tree calculation across
the service provider network and the destination multicast MAC address in BPDUs is
0x0100-0CCD-CDD0.
