Dynamic Routing / OSPF

OSPF support is available in software versions 10.7.1 and newer.

 

 

Configure OSPF Settings

Configured Router ID: Optionally enter a unique OSPF Router ID in the form of an IPv4 address or a number from 0 to 4294967295 (inclusive). This is the identifier that OSPF neighbors will see from the Ecessa device. This field can be left blank, in which case an identifier will be chosen using the IP address from one of the network interfaces.

Live Router ID: This field will display the actual Router ID currently being used by the device. If a Router ID was entered in the Configured Router ID field, that value will be displayed here. If a numerical value was entered it will be displayed as the equivalent IP address. If no Router ID value was entered then this field will display the chosen ID.

Redistribute Static: Check this box to enable the redistribution of configured static routes over OSPF. With this enabled, all static routes configured on the Ecessa device will be shared with OSPF area neighbors.

Routed Via: Optionally select one or more WANs where traffic from OSPF-discovered LAN routes will be routed without NAT. Click within this field to select WANs from the drop-down list. To remove previously selected entries click the X within the entry.

Configure these items with the desired values and click Activate.

To make the changes permanent, make sure the Save Changes box is checked before clicking "Activate".

Configure OSPF Areas

This is where OSPF areas can be added, modified, deleted, enabled, or disabled. OSPF networks can be split in to multiple areas to limit propagation of routing data to certain areas and increase efficiency. All existing areas will be displayed as a row in this table with the following columns:

Select: Clicking this box, or anywhere within the row, will highlight the row and select it for one of the operations.

Area ID: Each configured area ID will be displayed here as a link, which when clicked will open a window where area settings can be edited.

Enabled: This field will display a check mark if the corresponding area is currently enabled.

Stub: This field will display a check mark if the corresponding area is designated as an OSPF stub area. External routes are not flooded into stub areas.

The various actions can be performed on selected areas using the following buttons:

Add New Area: Click this button to configure and add a new OSPF area on the Ecessa device. A window will open where the new area can be configured.

Delete Selected Areas(s): Select one or more areas in the table then click this button to delete them. A confirmation dialog will appear to verify the operation.

Enable Area: After selecting an area that is currently disabled, clicking this button will enable the area.

Disable Area: After selecting an area that is currently enabled, clicking this button will disable the area.

Configure OSPF Area Settings

Configure the following settings when adding or modifying an OSPF area on the Ecessa device:

Area ID: When adding a new area, enter an OSPF area ID in the form of an IPv4 address or a number from 0 to 4294967295 (inclusive). The area ID should be chosen to match neighboring OSPF routers, and can not match any existing area on this Ecessa device. When editing an existing area, this field will display the area ID and can not be changed.

Area Enabled: Check this box to enable this area. Uncheck it to disable the area.

Stub Enabled: Check this box to designate this area as a stub area. External OSPF routes are not advertised in stub areas. Consult OSPF documentation to determine whether an area should be configured as a stub area or not.

Configure these items with the desired values and click Activate.

To make the changes permanent, make sure the Save Changes box is checked before clicking "Activate".

After activating a new area, or when editing an existing area, the following sections can also be configured. These are briefly described here, and are described in-depth in their own help pages:

Configure OSPF Interfaces: Add, modify, delete, and display OSPF Interfaces in this area.

Configure OSPF Area Networks: Add, modify, delete, and display OSPF area Networks in this area.

Configure OSPF Interfaces

Use this section to add, modify, or delete OSPF Interfaces on the Ecessa device. OSPF Area Interfaces are used to define which of the Ecessa device WAN and LAN networks are associated with the area, and the various settings to use for the interface. An interface can also be associated with Channel Bonding to communicate and share routes with remote sites. The Ecessa device will communicate with other OSPF routers only over configured OSPF interfaces. The table will display existing area interfaces and can be manipulated in the following ways:

  • Select a number in the Show entries drop-down to limit the number of entries to display per page.
  • Enter a search term in the Search field to filter the display to show only matching entries.
  • If there are more entries to display than the selected number of Show entries, then click Previous orNext to switch between pages of entries.
  • Click the Add New OSPF Interface button to configure and add a new interface to the table. A new window will appear where the interface settings can be entered. When correctly configured then click the "Add" button there to add the interface to the table.
  • Click on a row in the interface table and the following Action buttons will appear:
    • Edit: Click this button and a new window will open where the interface settings can be modified. When correctly configured then click the "Update" button there.
    • Delete: Click this button to delete the selected interface. A confirmation dialog will verify the operation.

These are the OSPF Interface configuration settings:

Interface Type: One of WAN, LAN, or Channel Bonding

Alias/Name: For type WAN or LAN this will be the name of the desired WAN or LAN.

Cost: Specifies output cost metric of the interface. For a given route, interfaces with the lowest cost number will be preferred.

Status: Enabled or Disabled

Hello Interval: The number of seconds between sending of OSPF Hello messages. This must be the same for all OSPF routers on the same network.

Stub: If Enabled, the Ecessa device will not listen for, or send, OSPF Hello messages on the interface.

Auth-Type: Must match OSPF neighbors. Can be one of the following:

      • None: Use no authentication on the interface.
      • Simple: Use weak authentication with 8 byte password.
      • Cryptographic: Use strong authentication with password encryption. Uses Keyed-MD5 algorithm for OSPF version 2 and HMAC-SHA-256 for OSPF version 3.

Password: For the "Simple" and "Cryptographic" types of authentication a password is required, which must match OSPF neighbors. Can be up to 32 characters, and can not include single or double quotes.

When an OSPF interface has been added or modified, the associated row will be highlighted in green as a reminder that Activate is required to save the changes.

Configure the interface settings with the desired values and click Activate.

To make the changes permanent, make sure the Save Changes box is checked before clicking "Activate".

OSPF Area Networks

Use this section to add, modify, and delete OSPF Area Networks. These Networks are definitions of area IP address ranges to advertise when originating OSPF Summary Link State Advertisements (LSA).

Network: Enter either an Alias (of type Address), an IP Address, or an IP subnet in IP/MASK format.

Add New OSPF Network: Click this button to add a Network to the table.

Delete: Click this button to delete the associated Network from the table.

After adding/deleting/modifying Networks click Activate.

To make the changes permanent, make sure the Save Changes box is checked before clicking "Activate".
