PIX OSPF Network
Configuring OSPF on your Security Appliance requires you to perform the following steps:
Step 1 Enable OSPF.
Step 2 Define the Security Appliance interfaces that need to run OSPF.
Step 3 Define OSPF areas.
Step 4 Configure LSA filtering to protect private addresses.
Using the configuration shown in Figure 11-2, the following commands configure OSPF
based on the scenario described:
pix515a(config)# router ospf 1
pix515a(config-router)# area 0 filter-list prefix ten in
pix515a(config-router)# network 192.168.0.0 255.255.0.0 area 0
pix515a(config-router)# network 172.16.1.0 255.255.255.0 area 172.16.1.0
pix515a(config-router)# network 10.10.10.0 255.255.255.0 area 10.10.10.0
pix515a(config-router)# prefix-list ten deny 10.10.10.0/24
pix515a(config)#
pix515a(config)# router ospf 1
pix515a(config-router)# prefix-list ten permit 172.16.1.0/24
pix515a(config)#
