Enabling connection forwarding
Under Connection Forwarding Settings, these configuration options are available:
Enable Connection Forwarding
Enables connection forwarding by default on all neighbors added to the peer list. The default value is 7850.
Port
Specifies the port number to use as the default for the neighbor appliance in-path port. The default value is 7850.
Keep-Alive Interval
Specifies the number of seconds to use as the default interval for ping commands between neighbor appliances. The default value is 1.
Keep-Alive Count
Specifies the number of tries to use as the default number of failed ping attempts before an appliance terminates a connection with a neighbor. The default value is 3.
In-Path Neighbor Failure
Uses the neighbor appliance to optimize new connections if the appliance fails.
For in-path deployments that use connection forwarding with WCCP, enabling this option ensures that if one appliance fails, the neighbor appliance continues to optimize new connections.
For in-path deployments that use connection forwarding without WCCP, enabling this option ensures that an appliance attempts to optimize new connections that are symmetrically routed, even after all of the neighbor appliances on another network path failed. New asymmetrically routed connections are not optimized but passed through.
Multiple Interface Support
Enables high availability on appliances configured with multiple in-path interfaces and using connection forwarding with another multiport SteelHead. This option makes all neighbor in-path interface IP addresses visible to each peer to ensure proper neighbor communication if the in-path0_0 interface fails.
RiOS 6.5 and later require connection forwarding in a WCCP cluster.
You must enable multiple interface support for a connection-forwarding neighbor to work with IPv6.
Adding a new neighbor
Under Neighbor Table, these configuration options are available:
Add a New Neighbor
Displays the controls to add a new neighbor.
Hostname
Specifies a hostname.
In-Path IP Address
Specifies the in-path IP address for the neighbor appliance. When you define a neighbor, you must specify the appliance in-path IP address, not the primary IP address.
You can use connection forwarding with IPv6 addresses if the following conditions are met:
• Both appliances must be running RiOS 9.6 or later.
• Multiple interface support must be selected.
• The IPv6 Connection Forwarding check box must be selected in the Connection Forwarding Settings area of this page.
Port
Specifies the in-path port for the neighbor appliance. The default port is 7850.
Additional IP Addresses
Adds a neighbor appliance to the neighbor list.
To modify the neighbor properties, select the IP address of the neighbor and complete the configuration.
