and VLAN ID 12, the virtual router displays the format in ASCII as 'west' '04' '1' '03'
'0008' '0012'.
You can use the l2tp disable calling-number-avp command to prevent the E Series LAC
from sending the Calling Number AVP in ICRQ packets. You use this command in special
situations where you do not want the LAC to send this AVP.
To prevent the LAC from sending the Calling Number AVP:
host1(config)#l2tp disable calling-number-avp
For more information about setting up the router to generate Calling Number AVP 22 in
a format that includes either or both of the agent-circuit-id and agent-remote-id
suboptions of the tags supplied by the PPPoE intermediate agent, see Configuring PPPoE
Remote Circuit ID Capture in the JunosE Link Layer Configuration Guide .
The following examples show how you can synchronize the contents of RADIUS
Calling-Station-Id (Attribute 31) and L2TP Calling-Number (AVP 22).
To send the PPPoE agent-circuit-id in RADIUS Attribute 31 and L2TP AVP 22 and specify
that the fixed format is used when the PPPoE agent-circuit-id is unavailable, issue the
following commands:
host1(config)#radius calling-station-format fixed-format
host1(config)#radius remote-circuit-id-delimiter #
host1(config)#radius override calling-station-id remote-circuit-id
host1(config)#radius remote-circuit-id-format agent-circuit-id
host1(config)#aaa tunnel calling-number-format include-agent-circuit-id
host1(config)#aaa tunnel calling-number-format-fallback fixed
To send the PPPoE agent-circuit-id and agent-remote-id in RADIUS Attribute 31 and
L2TP AVP 22 and specify that the fixed format is used when both PPPoE agent-circuit-id
and agent-remote-id are unavailable, issue the following commands:
host1(config)#radius calling-station-format fixed-format
host1(config)#radius remote-circuit-id-delimiter #
host1(config)#radius override calling-station-id remote-circuit-id
host1(config)#radius remote-circuit-id-format agent-circuit-id agent-remote-id
host1(config)#aaa tunnel calling-number-format include-agent-circuit-id
include-agent-remote-id
host1(config)#aaa tunnel calling-number-format-fallback fixed
The router uses either the local database related to the domain name or a RADIUS server
to determine whether to terminate or tunnel PPP connections.
For information about setting up RADIUS to provide this mapping, see "Configuring
Remote Access" on page 3.
For a given domain map, you can choose one of two methods to map the domain to an
L2TP tunnel locally on the router:
