Chapter 8. Command Reference 325
Caution: If the IP address of the remote tunnel is part of a subnet that is also reached through the tunnel, a routing
table entry for this address must be explicitly added. Normally, this routing entry will be added to remote entry,
which has the default route.
Note 1: When a remote router tries to create a tunnel, the remote routerÕs IP address is not authenticated .
Note 2: If this command is not used, then <ipaddr> defaults to 0.0.0.0, and this end cannot initiate the tunnel.
L2TP SET AUTHEN
Enables or disables authentication of the remote router during tunnel establishment using the CHAP secret, if it
exists. If the remote router tries to authenticate the local end during tunnel authentication, the local router will
always attempt to respond, provided a CHAP secret has been conÞgured.
L2TP SET CHAPSECRET
Creates a CHAP secret. This CHAP secret is used to authenticate the creation of the tunnel and is used for hiding
certain control packet information. The LAC and the LNS can share a single CHAP secret for a given tunnel.
l2tp set address <ipaddr> <TunnelName>
ipaddr IP address of the remote LAC or LNS.
TunnelName Name of the tunnel (character string). The name is case-sensitive.
Example:
l2tp set address 192.168.100.1 PacingAtWork
l2tp set authen on | off <TunnelName>
on Enables authentication.
off Disables authentication.
TunnelName Name of the tunnel (character string). The name is case-sensitive.
Example:
l2tp set authen PacingAtWork
l2tp set CHAPSecret <secret> <TunnelName>
secret CHAP secret (character string) used to authenticate the creation of the tunnel.
TunnelName Name of the tunnel (character string). The name is case sensitive.
Example:
l2tp set CHAPSecret PacingAtWork
