JunosE 11.3.x Broadband Access Configuration Guide
360
By default, the router uses the virtual router's router ID as the source address. You can
override this behavior for an L2TP tunnel by specifying a source address. If you do
specify a source address, use the address of a stable IP interface (for example, a
loopback interface). Make sure that the address is configured in the virtual router for
this domain map, and that the address is reachable by the peer.
Specify a tunnel identification. (The router groups L2TP sessions with the same tunnel
11.
identification into the same tunnel.)
host1(config-domain-map-tunnel)#identification acton
The router groups L2TP sessions with the same tunnel identification into the same
tunnel. This occurs only when both the destination (virtual router, IP address) and the
ID are the same.
Specify the L2TP tunnel type (RADIUS attribute 64, Tunnel-Type). Currently, the only
12.
supported value is L2TP.
host1(config-domain-map-tunnel)#type l2tp
Specify a medium type for the tunnel. (L2TP supports only IP version 4 [IPv4].)
13.
host1(config-domain-map-tunnel)#medium ipv4
(Optional) Specify a default tunnel client name.
14.
host1(config-domain-map-tunnel)#exit
host1(config-domain-map)#exit
host1(config)#aaa tunnel client-name boxford
If the tunnel client name is not included in the tunnel attributes that are returned from
the domain map or authentication server, the router uses the default name.
(Optional) Specify a default tunnel password.
15.
host1(config)#aaa tunnel password 3&92k%b#q4
host1(config)#exit
If the tunnel password is not included in the tunnel attributes that are returned from
the domain map or authentication server, the router uses the default password.
(Optional) Set the format for the tunnel assignment ID that is passed to PPP/L2TP.
16.
The tunnel assignment ID format can be either only assignmentID or clientAuthId +
serverAuthId + assignmentId.
host1(config)#aaa tunnel assignment-id-format assignmentID
If you do not set a tunnel assignment ID, the software sets it to the default
(assignmentID). This parameter is only generated and used by the L2TP LAC device.
(Optional) Specify whether or not to use the tunnel peer's Nas-Port [5] and
17.
Nas-Port-Type [61] attributes.
When enabled, the attribute is supplied by the tunnel peer. When disabled, the attribute
is not supplied. Use the no version of the command to restore the default, enable.
host1(config)#aaa tunnel ignore nas-port enable
host1(config)#aaa tunnel ignore nas-port-type disable
