Sample configuration: links crossing IP routers
Figure L-2 depicts a typical configuration of links crossing an IP router employing
LLT over UDP. The illustration shows two nodes of a four-node cluster.

The configuration that the following /etc/llttab file represents for Node 1 has
links crossing IP routers. Notice that IP addresses are shown for each link on each
peer node. In this configuration broadcasts are disabled. Hence, the broadcast
address does not need to be set in the link command of the /etc/llttab file.
