Configure IP Routes
Procedure for configuring IP routes for compute nodes. This is not required on a CLE system.
An /etc/sysconfig/network/routes file can provide route entries for compute nodes. This provides a mechanism for administrators to configure routing access from compute nodes to login and network nodes, using external IP destinations without having to traverse RSIP tunnels. Careful consideration should be given before using this capability for general purpose routing.
The /etc/sysconfig/network/routes file will provide a route from the compute nodes to a gateway node (login or network). However, that gateway node must provide a connection to the network of interest (via IP forwarding, NAT, or something else). These instructions do not cover providing that connection.
Use the simple_sync functionality to make the /etc/sysconfig/network/routes file available on the compute nodes.
The new /etc/sysconfig/network/routes file is examined during startup. Non-comment, non-blank lines are passed to the route add command. The empty file contains comments describing the syntax.
To make the routes file available to the compute nodes, do the following on the SMW.
