Verifying OSPF Support.
Use the
/info/net/route/ospf
menu to verify OSPF support on your Switched
Firewall.
Example 2: configuring GRE Tunnel
Figure 56
shows two Nortel Switched Firewalls, NSF- California and NSF-New York
configured for GRE tunneling support. The two firewalls are configured to tunnel OSPF
packets in a GRE tunnel, so other routers on the internet do not need to learn about OSPF.
In
Figure 56
the OSPF network is on the GRE interface 50.1.1.0/24; the GRE tunnel end points
is on physical interface 3.
