Setting Bpdu Tunneling For The Pvst Configuration - HP A5830 Configuration Manual

Setting BPDU tunneling for the PVST configuration

Network requirements
As shown in
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 of any VLAN to pass through.
 PVST is enabled for VLANs 1 through 4094 on User A's network.
After the configuration, CE 1 and CE 2 must implement consistent PVST calculation across the service
provider network, and the destination multicast MAC address carried in BPDUs must be 0x0100-0CCD-
CDD0.

# Disable STP on GigabitEthernet 1/0/1, and then enable BPDU tunneling for STP and PVST on it.
