Procedure
1. Configure PE 1:
# Set the destination multicast address to 0100-0ccd-cdd0 for tunneled packets.
<PE1> system-view
[PE1] l2protocol tunnel-dmac 0100-0ccd-cdd0
# Create VLAN 2.
[PE1] vlan 2
[PE1-vlan2] quit
# Configure Twenty-FiveGigE 1/0/1 as an access port and assign the port to VLAN 2.
[PE1] interface twenty-fivegige 1/0/1
[PE1-Twenty-FiveGigE1/0/1] port access vlan 2
# Disable STP and enable L2PT for STP on Twenty-FiveGigE 1/0/1.
[PE1-Twenty-FiveGigE1/0/1] undo stp enable
[PE1-Twenty-FiveGigE1/0/1] l2protocol stp tunnel dot1q
[PE1-Twenty-FiveGigE1/0/1] quit
# Configure Twenty-FiveGigE 1/0/2 connected to the service provider network as a trunk port,
and assign the port to all VLANs.
[PE1] interface twenty-fivegige 1/0/2
[PE1-Twenty-FiveGigE1/0/2] port link-type trunk
[PE1-Twenty-FiveGigE1/0/2] port trunk permit vlan all
[PE1-Twenty-FiveGigE1/0/2] quit
2. Configure PE 2 in the same way PE 1 is configured. (Details not shown.)
Verifying the configuration
# Verify that the root bridge of Customer A's network is CE 1.
<CE2> display stp root
MST ID Root Bridge ID ExtPathCost IntPathCost Root Port
0 32768.00e0-fc02-5800 0 0
# Verify that the root bridge of the service provider network is not CE 1.
[PE1] display stp root
MST ID Root Bridge ID ExtPathCost IntPathCost Root Port
0 32768.0cda-41c5-ba50 0 0
Example: Configuring L2PT for LACP
Network configuration
As shown in Figure 5, the MAC addresses of CE 1 and CE 2 are 0001-0000-0000 and
0004-0000-0000, respectively.
Perform the following tasks:
• Configure Ethernet link aggregation on CE 1 and CE 2.
• Configure Twenty-FiveGigE 1/0/1 and Twenty-FiveGigE 1/0/2 on CE 1 to form aggregate links
with Twenty-FiveGigE 1/0/1 and Twenty-FiveGigE 1/0/2 on CE 2, respectively.
• Enable L2PT for LACP to enable CE 1 and CE 2 to implement Ethernet link aggregation
across the service provider network.
