Setting Routes
The process of routing packets consists of selectively forwarding data packets
from one network to another. Your router makes a decision to send a packet to
a particular network on information it learns dynamically from listening to the
selected route protocol and on the static information entered as part of the
configuration process. In addition, you can configure user-defined filters to
restrict the way packets are sent.
Your router maintains a table of routes which holds information about routes to
destinations. The route table tells the router how to find a remote network or
host. A route is uniquely identified by IP address, network mask, next hop,
ifIndex, protocol and policy. A list of routes comprises all the different routes to
a destination. The routes may have different metrics, next hops, policy or
protocol. A list of routes is uniquely identified by its IP address and net mask.
The routing table is maintained dynamically by using one or more routing
protocols such as RIP, EGP and OSPF. These act to exchange routing
information with other routers or hosts.
You can also add static routes to the route table to define default routes to
external routers or networks and to define subnets.
To add a static route, enter the command:
ADD IP ROUTE=ipadd INTERFACE=interface NEXTHOP=ipadd
[CIRCUIT=miox-circuit] [DLCI=dlci]
[MASK=ipadd][METRIC=1..16] [METRIC1=1..16]
[METRIC2=1..65535][POLICY=0..7] [PREFERENCE=0..65535]
To displays the entire routing table, including both static and dynamic routes,
enter the command:
SHOW IP ROUTE
For more information about setting IP routes, see the Internet Protocol (IP)
chapter in the AR400 Series Router Software Reference.
Changing a Password
You should change this password to prevent unauthorised access to the router.
Enter the command:
SET PASSWORD
The router prompts you for the current password, for the new password, and
for confirmation of the new password. The password can contain any printable
characters, and must be at least a minimum length, by default six characters.
(To change the default minimum length, see the SET USER command in the
Operations chapter, AR400 Series Router Software Reference.)
