Configuring an ANG-3000/7000
4 From the OSPF Authentication Algorithm menu, choose the
authentication algorithm used by routers on your network.
If the routers on your network do not require passwords to accept
OSPF updates, set the algorithm to None and continue with the next
step.
5 Do one of the following:
– Click Apply to save your changes.
– Click Cancel to close the window without saving your changes.
– Click Reset to the return the OSPF properties to their default
settings.
Routing Interfaces
The ANG is equipped with two Ethernet interfaces:
H The Trusted interface should be connected to a protected network
segment (one behind a firewall or router that offers protection against
unauthorized access). Typically, you should enable a routing protocol
(RIP, OSPF, or both) on the Trusted interface so that the ANG can
advertise to other devices that its virtual subnets are reachable to the
corporate network.
H The External interface can be connected to a network segment that
resides outside a firewall and offers unfiltered access to the Internet.
You must create a static route between the External interface and the
router that serves as the gateway to the Internet. You cannot enable
RIP or OSPF on this interface.
