105Configuring destination multicast MAC address for BPDUsBy default, the destination multicast MAC address for BPDUs is 0x010F-E200-0003. You can change itto 0x0100-0CCD-CDD0, 0x0100-0CCD-CDD1 or 0x0100-0CCD-CDD2 through the followingconfiguration.To configure the destination multicast MAC address for BPDUs:Step Command Remarks1. Enter system view. system-view N/A2. Configure the destinationmulticast MAC address forBPDUs.bpdu-tunnel tunnel-dmacmac-addressOptional.The default setting is0x010F-E200-0003.NOTE:For BPDUs to be recognized, the destination multicast MAC addresses configured for BPDUs must be thesame on the edge routers on the service provider network.BPDU tunneling configuration exampleNetwork requirementsAs shown in Figure 38:• CE 1 and CE 2 are edges routers on the geographically dispersed network of User A; PE 1 and PE2 are edge routers on the service provider network.• All ports that connect service provider and customer routers are access ports and belong to VLAN2; all ports that connect service provider routers are trunk ports and allow packets of any VLAN topass through.• MSTP is enabled on User A network.Configure BPDU tunneling, so that CE 1 and CE 2 implement consistent spanning tree calculation acrossthe service provider network and the destination multicast MAC address in BPDUs is0x0100-0CCD-CDD0.Figure 38 Network diagramConfiguration procedure1.
