Juniper JUNOSE SOFTWARE 11.2.X - BROADBAND ACCESS CONFIGURATION GUIDE 7-20-2010 Configuration Manual page 391

You can specify up to eight levels of preference, and you can assign the same
preference to a maximum of 31 tunnels. When you define multiple preferences for
a destination, you increase the probability of a successful connection.
host1(config-domain-map-tunnel)#preference 5
(Optional) Specify an authentication password for the tunnel.
7.
host1(config-domain-map-tunnel)#password temporary
NOTE: If you specify a password for the LAC, the router requires that the peer (the LNS)
authenticate itself to the router. In this case, if the peer fails to authenticate itself, the
tunnel terminates.
(Optional) Specify a hostname for the LAC end of the tunnel.
8.
The LAC sends the hostname to the LNS when communicating to the LNS about
the tunnel. The hostname can be up to 64 characters (no spaces).
host1(config-domain-map-tunnel)#client-name host4
NOTE: If the LNS does not accept tunnels from unknown hosts, and if no hostname is
specified, the LAC uses the router name as the hostname.
(Optional) Specify a server name for the LNS.
9.
This name specifies the hostname expected from the peer (the LNS) when you set
up a tunnel. When this name is specified, the peer must identify itself with this name
during tunnel startup. Otherwise, the tunnel is terminated. The server name can be
up to 64 characters (no spaces).
host1(config-domain-map-tunnel)#server-name boston
(Optional) Specify a source IP address for the LAC tunnel endpoint. All L2TP packets
10.
sent to the peer use this source address.
host1(config-domain-map-tunnel)#source-address 192.0.3.3
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
11.
tunnel 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
12.
only supported value is L2TP.
