(Optional) Specify an authentication password for the tunnel.
6.
host1(config-tunnel-group-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.
7.
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-tunnel-group-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.
8.
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-tunnel-group-tunnel)#server-name boston
(Optional) Specify a source IP address for the LAC tunnel endpoint. All L2TP packets
9.
sent to the peer use this source address.
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.
host1(config-tunnel-group-tunnel)#source-address 192.0.3.3
Specify a tunnel identification.
10.
host1(config-tunnel-group-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 a medium type for the tunnel. (L2TP supports only IP version 4 [IPv4].)
11.
host1(config-tunnel-group-tunnel)#medium ipv4
Specify the L2TP tunnel type (RADIUS attribute 64, Tunnel-Type). Currently, the only
12.
supported value is L2TP.
host1(config-tunnel-group-tunnel)#type l2tp
Verify the L2TP tunnel configuration.
