Configuring IPv4 OSPFv2 in Gaia Clish

Important: In a Cluster Two or more Security Gateways that work together in a redundant configuration - High Availability, or Load Sharing., you must configure all the Cluster Members in the same way. Start the OSPF configuration from Router ID (see Configuring IPv4 OSPFv2 Router ID). Gaia Clish The name of the default command line shell in Check Point Gaia operating system. This is a restricted shell (role-based administration controls the number of commands available in the shell). does not have commands for route filtering and redistribution. You must configure inbound routing policies and redistribution of routes through the Gaia Portal Web interface for the Check Point Gaia operating system.. You can configure route maps and route aggregation using Gaia Check Point security operating system that combines the strengths of both SecurePlatform and IPSO operating systems. Clish commands. Route map configuration done through the Gaia Clish takes precedence over route filtering and redistribution configured in the Gaia Portal. For example, if OSPF uses route maps for inbound filtering, anything configured in the Gaia Portal for inbound route filters for OSPF is ignored. You can still use the Gaia Portal to configure route redistribution into OSPF.

Procedure

1. Connect to the command line.

2. Log in to Gaia Clish.

3. Configure the Router ID.

   See Configuring IPv4 OSPFv2 Router ID.

4. Optional: Configure additional OSPF Areas (in addition to the backbone area).

   See Configuring IPv4 OSPFv2 Areas in Gaia Clish.

5. Configure the Global Options.

   See Configuring IPv4 OSPFv2 Global Options in Gaia Clish.

6. Optional: For each OSPF Area, you can add one or more IPv4 address ranges, if you want to reduce the number of routing entries that the OSPF Area advertises into the OSPF backbone.

   Note - To prevent an address range from being advertised into the backbone, select the option Restrict for the address range

7. Configure OSPF Interfaces.

   See Configuring IPv4 OSPFv2 Interfaces in Gaia Clish.

8. Optional: Configure the OSPF Instances.

   See Configuring IPv4 OSPFv2 Multiple Instances.

9. Configure OSPF Virtual Links for any area that does not connect directly to the backbone area.

   See Configuring IPv4 OSPFv2 Virtual Links in Gaia Clish.

10. Save the configuration:
