Procedure
Step 1 Assign an IP address to each loopback interface and configure a VT interface and a BAS
interface.
<Router> system-view
[Router] sysname LAC1
# Assign an IP address to a loopback interface directly connecting LAC1 to the LNS so that the
route to the loopback interface can be advertised.
[LAC1] interface loopback1
[LAC1-loopback1] ip address 7.7.7.7 32
[LAC1-loopback1] quit
# Assign an IP address to a loopback interface directly connecting LAC1 to the LAC2 so that
the route to the loopback interface can be advertised.
[LAC1] interface loopback2
[LAC1-loopback2] ip address 8.8.8.8 32
[LAC1-loopback2] quit
# Configure VT interface 1.
[LAC1] interface virtual-template 1
[LAC1-Virtual-Template1] ppp authentication-mode chap
[LAC1-Virtual-Template1] quit
# Bind VT interface 1 to GE 1/0/0.1 and configure a user VLAN.
[LAC1] interface gigabitethernet 1/0/0.1
[LAC1-GigabitEthernet1/0/0.1] pppoe-server bind virtual-template 1
[LAC1-GigabitEthernet1/0/0.1] user-vlan 1 100
[LAC1-GigabitEthernet1/0/0.1-vlan-1-100] quit

is used in this example. For details about configurations on LAC2, see the configuration file of LAC2.
VRRP parameters such as a VRID and a preemption delay
BFD parameters such as the local and remote discriminators and expected minimum
interval at which BFD Control packets are sent and received
IP address of each interface on LAC1 and LAC2
Backup ID, which works together with an RBS to identify an RBP to which users belong
User access parameters
L2TP group parameters such as an authentication password and an interval at which Hello
