54.3 PPPoE Intermediate Agent Typical Application
PPPoE Intermediate Agent typical application is as follows:
Figure 54.5: PPPoE IA typical application
Both host and BAS server run PPPoE protocol, they are connected by layer 2 ethernet, switch
enables PPPoE Intermediate Agent function.
Typical configuration (1) in the following:
Step 1: Switch enables global PPPoE IA function, MAC as 0a0b0c0d0e0f.
Switch(config)#pppoe intermediate-agent
Step 2: Configure port ethernet1/0/1 which connect server as trust port, and configure vendor
tag strip function.
Switch(config-if-ethernet1/0/1)#pppoe intermediate-agent trust
Switch(config-if-ethernet1/0/1)#pppoe intermediate-agent vendor-tag strip
Step 3: Port ethernet1/0/2 of vlan1 and port ethernet1/0/3 of vlan 1234 enable PPPoE IA
function of port.
Switch(config-if-ethernet1/0/2)#pppoe intermediate-agent
Switch(config-if-ethernet1/0/3)#pppoe intermediate-agent
Step 4: Configure pppoe intermediate-agent access-node-id as abcd.
Switch(config)#pppoe intermediate-agent type tr-101 circuit-id access-node-id abcd
Step 5: Configure circuit ID as aaaa, remote ID as xyz for port ethernet1/0/3.
Switch(config-if-ethernet1/0/3)#pppoe intermediate-agent circuit-id aaaa
Switch(config-if-ethernet1/0/3)#pppoe intermediate-agent remote-id xyz
circuit-id value is 'abcd eth 01/002:0001', remote-id value is '0a0b0c0d0e0f' for the added ven-
dor tag of port ethernet1/0/2. circuit-id value is 'aaaa', remote-id value is 'xyz' for the added vendor
tag of port ethernet1/0/3.
Typical configuration (2) in the following:
Step 1: Switch enables global PPPoE IA function, MAC as 0a0b0c0d0e0f.
