CVX Multi-Service Access Switch 4.1 Release Notes
Vrouter support for L2TP and ClearTCP
The CVX switch previously supported the use of vrouters for PPP calls, but now
also supports L2TP and ClearTCP calls. This eliminates the need to add routes for
L2TP and ClearTCP in the default routing table.
All traffic for an L2TP or ClearTCP call will be routed using the vrouter specified
in the VPOP for the call. In addition, all RADIUS traffic for the call will also be
routed using the vrouter.
The vrouter will work with whatever network type is used to connect the CVX
switch to the wholesale customer’s network, including frame relay and Ethernet.
For configuration of vrouters, see “Configuring the IP_Vrouter Objects” (page
5-29), in the CVX Multi-Service Access Switch Configuration Guide.
Add a route to the vrouter that points to the interface that the RADIUS server in
question is on. It need only be a host route, if the only destination is the RADIUS
server, or it can be a wider route, if necessary. If the RADIUS server is on the
same segment as the CVX interface, the next hop value of the route can be
anything on that segment, and is best set to the RADIUS server itself.
Note: Due to hardware limitations, V.44 will not be supported on the CSM3
MAC cards.
Note: Before the changes in vrouter functionality, RADIUS traffic was routed
using the default router and not the vrouter for the VPOP. With the changes
made in the vrouter functionality, RADIUS traffic is now sent using vrouters.
Changes may be required in the default routing table and vrouter routes. The
vrouter configured for a VPOP should have routes which allow it to get to the
RADIUS servers used for the VPOP.
