Routing Interfaces
The ANG is equipped with two Ethernet interfaces:
H The Trust ed 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.
