-l2tpns is half of a complete L2TP implementation. It supports only the
-
LNS side of the connection.<P>
+l2tpns a complete L2TP implementation. It supports the LAC, LNS and
L2TP (Layer 2 Tunneling Protocol) is designed to allow any layer 2
protocol (e.g. Ethernet, PPP) to be tunneled over an IP connection. l2tpns
If no address is given to iftun_address and bind_address, 1.1.1.1 is used.
</LI>
+<LI><B>bind_multi_address</B> (ip address)<BR>
+This parameter permit to listen several addresss of the l2tp udp protocol
+(and set several address to the tun interface).
+<BR>
+WHEN this parameter is set, It OVERWRITE the parameters "bind_address"
+and "iftun_address".
+<BR>
+these can be interesting when you want do load-balancing in cluster mode
+of the uploaded from the LAC. For example you can set a bgp.prepend(MY_AS)
+for Address1 on LNS1 and a bgp.prepend(MY_AS) for Address2 on LNS2
+(see BGP AS-path prepending).
+<BR>
+example of use with 2 address:
+<BR>
+set bind_multi_address "64.14.13.41, 64.14.13.42"
