OSPF Configuration
Configuring OSPF on Gigabit Ethernet
Sample Gigabit Ethernet interface configuration
Figure 6-5 shows three OSPF routers in the backbone area of an autonomous system.
Because all OSPF routers are in the same area, the routers form adjacencies and
synchronize their databases. This example shows how to configure the Gigabit
Ethernet interface of the unit labeled Stinger-2.
Figure 6-5. OSPF on a LAN interface
All OSPF routers in Figure 6-5 have RIP turned off. Running both RIP and OSPF is
unnecessary, and turning RIP off reduces processor overhead. OSPF can learn routes
from RIP interfaces, incorporate them in the routing table, assign them an external
metric, and tag them as external routes.
Although RFC 2328 does not specify a limitation for the number of routers in the
backbone area, keep the number of routers relatively small, because changes that
occur in area zero are propagated throughout the autonomous system. Another way
to configure the same units is to create a second area (such as 0.0.0.1) in one of the
existing OSPF routers, and add the Stinger IP2000 to that area. You can then assign
the same area number (0.0.0.1) to all OSPF routers reached through the Stinger
IP2000 across a WAN link.
The following sample commands show how to configure Stinger-2 in Figure 6-5.
The commands assign the IP address 10.168.8.17/24 to the local interface and
configure the OSPF router in the backbone area:
admin> read ip-interface { { 1 8 2 } 0 }
admin> set ip-address = 10.168.8.17/24
admin> set rip-mode = routing-off
admin> set ospf active = yes
admin> write -f
The following sample commands show how to configure the IP interface for MD5
authentication:
admin> read ip-interface { { 1 8 2 } 0 }
admin> set ospf authen-type = md5
admin> set ospf md5-auth-key = 12!secret*34key
admin> write -f
