Setting Up Virtual Private Networks
Configuring Virtual Routers
for the destination address to the specified VRouter, which consults its own routing table to
further route the packets. For example:
Dest=10.207.23.1
Gateway=0.0.0.0
Virtual Router=vr1
Dest VRouter=vr2
In this previous example, the Dest parameter, specifies the destination IP address, 10.207.23.1.
Specifying the name of another active virtual router, vr2, in the Dest VRouter parameter
indicates that there is a static route between the VRouters. The Virtual Router parameter
specifies the name of the Virtual Router (VRouter) for which the MAX unit creates the Static
Route. It is the same name as the one specified in the Virtual Routers profile, vr1.
Disabling a Virtual Router profile
Disabling a Virtual Router profile disables the VRouter itself. For example:
Active=No
If you disable a VRouter with active connections, you should reset the MAX unit. If you
cannot reset the unit, manually tear down any active connections, and then modify the local
Connection and Static Rtes profiles that point to the VRouter. Specify that the local
Connection and Static Rtes profiles to point to the global VRouter or another existing VRouter.
VRouter support for L2TP tunneling
A MAX unit using RADIUS authentication and functioning as an L2TP Access Concentrator
(LAC) can provide Virtual Routers (VRouters) for L2TP sessions. The RADIUS attribute
Ascend-Tunnel-Vrouter-Name enables you to specify a VRouter.
The VRouter name you specify must also be specified by the Ethernet > Mod Config > L2
Tunneling Options > System Name parameter. Otherwise, the tunneling connection reverts to
the MAX unit’s main router.
Note: With the implementation of virtual routers within ATMP, you can now split the MAX
unit into as many FA/HA you need. This is limited only by the number of virtual routers
configured on a MAX unit.
Configuring VRouter support for IPX networks
Virtual router (VRouter) support for secure, private IPX networks enables the creation of
multiple virtual IPX routers in a single MAX unit. The VRouter feature for IPX networks is an
extension of the VRouter feature for the IP networks. The IP vRouter feature logically groups
the interfaces to provide secure, private IP networks. Each of these private networks maintains
its own
• IP routing table
• ARP entries table
• IP route cache
• IP address pools
