Configuring The Local Address And The Address Pool For Allocation - 3Com MSR 50 Series Configuration Manual

Configuring the Local
Address and the Address
Pool for Allocation
If you enable LCP negotiation but do not configure authentication for the
corresponding virtual interface template, the LNS will not perform addition
authentication of users (In this case, users are authenticated only once on the LAC)
and will directly allocate addresses from the global address pool to the users.
Follow these steps to specify to perform LCP negotiation with users:
To do...
Enter system view
Enable L2TP
Create an L2TP group and
enter its view
Specify to perform LCP
negotiation with users
After an L2TP tunnel is set up between an LAC and an LNS, the LNS needs to
allocate an IP address from its address pool to a VPN user. Before specifying an
address pool, use the ip pool command in system view or ISP domain view to
define the address pool. For detailed description about the ip pool command,
refer to "AAA/RADIUS/HWTACACS Configuration" on page
prefers the address pool configured in domain view when allocating an IP address
to a VPN user.
Follow these steps to configure a local address and address pool:
To do...
Enter system view
Create a virtual interface
template and enter its view
Configure the local IP address ip address ip-address { mask |
Configure the authentication
mode for PPP users
Specify the address pool for
allocating an address to a VPN
user
Use the command...
system-view
l2tp enable
l2tp-group group-number
mandatory-lcp
Use the command...
system-view
interface virtual-template
virtual-template-number
mask-length } [ sub ]
ppp authentication-mode
{ chap | pap } [ call-in |
domain isp-name ]
remote address { pool
[ pool-number ] | ip-address }
