Routing connectivity methods

Routing deals with what path the network traffic follows from its source to its destination and how that path is connected.

Routing with point-to-point connections
Using point-to-point connections, you can send your data from your local system to a remote system or from a local network to a remote network.
Proxy Address Resolution Protocol routing
Proxy Address Resolution Protocol (ARP) provides connectivity between physically separate networks without creating any new logical networks and without updating any routing tables. This topic also contains a description of transparent subnets, which is an extension to the proxy ARP routing technique.
Dynamic routing
Dynamic routing is a low-maintenance method that automatically reconfigures routing tables when your network changes.
Dead gateway detection
Dead gateway detection automatically detects a failed "next-hop" gateway, allowing alternative routes to be used until the gateway recovers.
Route binding
Route binding gives you control over which interface is used to send out response packets of information.
Classless Inter-Domain Routing
Classless Inter-Domain Routing can reduce the size of your routing tables and make more IP addresses available within your business.
Routing with virtual IP
Virtual IP, also called a circuitless or loopback interface, is a powerful function that provides a way to assign one or more addresses to the system without the need of binding the address to a physical interface.
Fault tolerance
Another use of virtual IP addresses is to protect against router failures. Fault tolerance shows several different ways a route might be recovered after an outage.
Routing with network address translation
Routing with network address translation (NAT) allows you to access remote networks, such as the Internet, while protecting your private network by masking IP addresses that are used on the private network.
Routing with OptiConnect and logical partitions
OptiConnect can connect multiple IBM® i platforms by using a high-speed, fiber-optic bus. OptiConnect and logical partitions provide other environments for you to use the routing basics of proxy ARP, point-to-point, and virtual IP interfaces.
