Configuring IP routes
MAX 6000/3000 Network Configuration Guide 9-59
If a Framed-Route definition in a user profile duplicates a route defined in a route or IP-Route
profile, the user profile definition takes precedence while the connection is active. For
example, suppose a static route to network 10.10.10.10 is defined in a local IP-Route profile
with a metric of 10. A RADIUS user profile in RADIUS defines a static route to 10.10.10.10
with a metric of 7. When the RADIUS user’s route is not in use, the routing table indicates that
the route has a metric of 10. When the route is in use, the MAX routing table indicates that the
route has a metric of 7, with an
r in the flags column to indicate that the route came from
RADIUS. Furthermore, the route with a metric of 10 remains in the routing table, with an
asterisk (*) in the flags column, indicating that it is a hidden route.
Connection-specific private static routes (RADIUS only)
The following attribute-value pairs configure IP options in a RADIUS profile:
Configuring the default route
If no routes exist for the destination address of a packet, the MAX forwards the packet to the
default route. Most sites use the default route to off-load routing tasks to other devices, such as
a local IP or a UNIX host running the route daemon.
Note: If the MAX does not have a default route, it drops packets for which it has no route.
To configure the default route:
1 Open the first IP Route profile (the route named Default) and activate it:
Ethernet
Static Rtes
Default
Name=Default
Active=Yes
Dest=0.0.0.0/0
Note: The name of the first Static Rtes profile is always Default, and its destination is
always 0.0.0.0. You cannot change these values.
2 Specify the router to use for packets with unknown destinations. For example:
Gateway=10.9.8.10
3 Specify a metric for this route, the route’s preference, and whether the route is private. For
example:
Metric=1
Preference=100
Private=Yes
4 Exit the profile and, at the exit prompt, select the exit and accept option.
Following is a comparable RADIUS default route:
route-max-1 Password = "ascend", Service-Type = Outbound-User
Framed-Route = "0.0.0.0 10.9.8.10 1 y 100"
Attribute Value
Ascend-Private-Route
(104)
A private framed route known only to the profile in which it is
specified. The value is a destination address and next-hop router
address (in that order).
