Procedure
Step 1 Configure VLANs to which the interfaces belong according to
The configuration details are not mentioned here.
Step 2 Configure IGP on the MPLS backbone network so that PEs and P devices can interwork with
each other.
# Configure PE1.
# Assign IP addresses to interfaces. The IP address of a loopback interface must have a 32-bit
mask.
<PE1> system-view
[PE1] interface loopback 1
[PE1-LoopBack1] ip address 1.1.1.1 32
[PE1-LoopBack1] quit
[PE1] interface vlanif 10
[PE1-Vlanif10] ip address 100.1.1.1 30
[PE1-Vlanif10] quit
# Configure IS-IS to advertise routes on interfaces.
[PE1] isis 1

Configure BGP/MPLS IP VPN.
In the BGP view of CE1, enable load balancing for the traffic transmitted from CE1 to CE2.
Increase the MED value of the BGP-VPN route on PE3. In this way, CE2 selects PE4 as
the next hop to CE1.
