You need to verify that the appropriate routes are configured.
Your server needs routes to send packets to other servers or hosts. The
route determines the path that a packet takes to its destination.
If you are trying to ping an interface address and do not receive a reply,
you should verify that your routes are configured and available. To communicate
between a local and remote network, whether you are using IPv4 or IPv6 connectivity,
you should have at least these two types of routes configured on the server:
- A direct route (*DIRECT) allows packets to travel between interfaces on
the local network. It is automatically configured and activated by the server
for each interface.
- A default route (*DFTROUTE) allows packets to travel to hosts that are
not directly connected to your network. It provides a path for the packets
to take. A default route identifies a specific node as a next hop to which
the packets travel and then continue their trip to their final destination
on a different network. The packets take the default route whenever there
is no other (more specific) route matching the destination IP address.
Keep in mind that routes are unidirectional. Just because a packet from
a client can get to your server does not mean that your server can send a
packet to the client.
IPv4 routes
To display information about the IPv4
routes on your server, follow these steps:
- In iSeries™ Navigator,
expand your .
- Select Routes.
- Right-click the IP address in the Remote Network column of the route you
want to see, and select Properties.
- If you do not have a default route configured, you should configure it
now. To configure an IPv4 default route, follow these steps:
- In iSeries Navigator,
expand your .
- Right-click Routes and select New Route.
- Follow the wizard's instructions to create a new default route.
IPv6 routes
To display information about the IPv6
routes on your server, follow these steps:
- In iSeries Navigator,
expand your .
- Select Routes.
- Right-click the IP address in the Destination Address column of the route
you want to see, and select Properties.
- For IPv6, the Internet Protocol automatically configures default routes
for each interface on the server. However, if you prefer, you can use the New
IPv6 Route wizard in iSeries Navigator to create new IPv6
routes yourself. To configure an IPv6 default route, follow these steps:
- In iSeries Navigator,
expand your .
- Right-click Routes and select New Route.
- Follow the wizard's instructions to create a new default route.
