Configuring Route Management Redundancy

Route management redundancy requires the following:

  • Two Ethernet interfaces that are configured for different networks. One is the default interface that contains the default gateway configuration. The second interface provides static routes that use a different next-hop gateway.
  • A virtual IP address for the CTP device. To create a list of the virtual IP addresses that will be associated with the CTP device, select Node > Maintenance > Configure Virtual IPs, and follow the instructions on the pane. You can create up to 56 virtual IP addresses.
  • CTP bundle circuits that use route redundancy should have direct drive disabled to allow for asymmetric routing. See Configuring IP Forwarding for CTP Bundles (CTPView) or Configuring IP Forwarding for CTP Bundles (CTP Menu)

To set up route management redundancy, perform the following tasks:

  1. Configuring the Default Ethernet Interface (CTP Menu)
  2. Configuring an Ethernet Interface With Static Routes (CTP Menu)
  3. Enabling Route Management Redundancy (CTPView)

Configuring the Default Ethernet Interface (CTP Menu)

You are required to reboot the CTP device when you finish this configuration procedure.

To configure the default Ethernet interface using the CTP Menu:

  1. From the Main menu, select 5) Node Operations.
  2. Select 3) Configure network settings.
  3. Select 2) IPv4 Configuration or 3) IPv6 Configuration.
  4. Follow the onscreen instructions to select and specify a default Ethernet interface.
  5. Configure the options as described in Table 1.

    Do not add a route to the default Ethernet interface.

Table 1: Ethernet Interface Parameter Settings in the CTP Menu

FieldFunctionYour Action

Please input the hostname

Specifies the host name for the CTP device.

Enter a name.

Please input the ip/ipv6

Specifies the IP address of the Ethernet interface.

Enter an IP address.

Please input the netmask

For IPv4 interfaces, specifies the network mask.

Enter the network mask.

Please input the gateway

On the default Ethernet interface, specifies the IP address of the default next-hop gateway, which is the Ethernet interface on the the router.

Enter an IP address.

Please input the mtu in bytes

Specifies the maximum transmission unit (MTU) for the Ethernet interface.

For IPv4 networks, enter a number from 64 through 1500.

For IPv6 networks, enter a number of at least 1280.

Configuring an Ethernet Interface With Static Routes (CTP Menu)

Configure an Ethernet interface on a network that is different from the default Ethernet interface, and add static routes to the interface configuration.

You are required to reboot the CTP device when you finish this configuration procedure.

To configure static routes for Ethernet interfaces using the CTP Menu:

  1. From the Main menu, select 5) Node Operations.
  2. Select 3) Configure network settings.
  3. Select 2) IPv4 Configuration or 3) IPv6 Configuration.
  4. Follow the onscreen instructions to select a second Ethernet interface to activate on boot, and configure the options as described in Table 2.

Table 2: Ethernet Parameter Settings in the CTP Menu

FieldFunctionYour Action

Please input the ip/ipv6

Specifies the IP address of the Ethernet interface.

Enter an IP address.

Please input the netmask

For IPv4 interfaces, specifies the network mask.

Enter the network mask.

Please input the mtu in bytes

Specifies the maximum transmission unit (MTU) for the Ethernet interface.

For IPv4 networks, enter a number from 64 through 1500.

For IPv6 networks, enter a number of at least 1280.

Add route to interface eth

Specifies whether or not to add static routes to the Ethernet configuration.

Specify yes.

How many routes would you like to add to eth0?

Specifies the number of static routes to add to your Ethernet interface configuration.

Enter a number between 0 and 3.

Please input the network

Specifies the IP address of the static route to the next-hop gateway.

Enter an IP address.

Please input the number of bits in the netmask

For IPv4 networks, specifies the IP mask of the Ethernet interface.

Enter an IP mask.

Please input the gateway

Specifies the IP address of the next-hop gateway (the router).

Enter an IP address.

Enabling Route Management Redundancy (CTPView)

This topic describes how to enable the route redundancy management feature.

To enable route management redundancy using CTPView:

  1. In the side pane, select System > Configuration.
  2. Set the AutoSwitch Daemon parameter to Enabled.
  3. Click AutoSwitch.
  4. Under AutoSwitch Ethernet Failover Settings, configure the parameters described in Table 3, and click Submit Settings.

Table 3: Route Management Redundancy Settings in CTPView

FieldFunctionYour Action

Route Management Redundancy

Enables or disables route management redundancy

Select one:

  • Enabled
  • Disabled

Check Period

This parameter is under the AutoSwitch Bundle Failover Settings configuration in CTPView.

Specifies the frequency with which the CTP software runs a reachability check. For example, if the check period is set for 30, the CTP software checks if the next-hop is reachable once every 30 seconds.

Select the number of seconds.
