Configuring system-level routing policies
Depending on the requirements of your network environment, yo u need to configure
system-global routing policies in addition to the LAN interface. Services available for the
MAX include:
•Dynamic IP addressing
•Boot Protocol (BOOTP) requests
•Name resolution services: Domain Name System (DNS) and Windows Internet Name
Service (WINS)
•Dynamic Host Configuration Protocol (DHCP)
•Network Address Translation (NAT)
Additional system-level services include system time, Telnet password, shared Connection
profiles, suppression of dial-out route advertisement in redundant configurations when a trunk
fails, UDP checksums, and suppression of host route advertisements.
For detailed information about each parameter in the following sections, see the MAX
Reference.

Dynamic IP addressing for dial-in hosts

For dial-in PPP clients not running as IP routers, the MAX can assign each connection to a
local IP address on a first-come, first-served basis. After the connection is terminated, the
address that was assigned to that connection is returned to the pool for reassignment to another
connection.

Enabling dynamic address assignment

To enable the MAX for dynamic address assignment, you set the Assign Address parameter in
the Answer profile to Yes.

Specifying address pools

In addition, to enable dynamic addressing, you must set the address pool parameters in the
Ethernet > Mod Config > WAN Options menu. You can configure a MAX unit to contain as
many as 10 address pools of as many as 254 addresses for dynamic assignment, as described in
the following sections.
Set the Pool#N Start parameter to specify the first address in a block of contiguous addresses
on the local network or subnet. Set the Pool#N Count parameter to specify how many
addresses are in the pool (up to 254).
Addresses in a pool do not accept a subnet mask, because they are advertised as host routes. If
you allocate IP addresses on a separ ate IP network or subnet, make sure yo u inform other IP
routers about the route to that network or subnet, either by statically configuring those routes
or by configuring the unit to dynamically send updates.
