Sample configuration: links crossing IP routers

Figure: A typical configuration of links crossing an IP router 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 IPv6 addresses are shown for each link on each peer node. In this configuration multicasts are disabled.

set-node Node1
set-cluster 1

link link1 /dev/udp6 - udp6 50000 - fe80::21a:64ff:fe92:1a92 - 
link link1 /dev/udp6 - udp6 50001 - fe80::21a:64ff:fe92:1a93 -

#set address of each link for all peer nodes in the cluster
#format: set-addr node-id link tag-name address
set-addr 0 link1 fe80::21a:64ff:fe92:1b46 
set-addr 0 link2 fe80::21a:64ff:fe92:1b47 
set-addr 2 link1 fe80::21a:64ff:fe92:1d70 
set-addr 2 link2 fe80::21a:64ff:fe92:1d71 
set-addr 3 link1 fe80::209:6bff:fe1b:1c94 
set-addr 3 link2 fe80::209:6bff:fe1b:1c95 

#disable LLT multicasts
set-bcasthb     0
set-arp         0

The /etc/llttab file on Node 0 resembles:

set-node Node0
set-cluster 1

link link1 /dev/udp6 - udp6 50000 - fe80::21a:64ff:fe92:1b46 - 
link link2 /dev/udp6 - udp6 50001 - fe80::21a:64ff:fe92:1b47 -

#set address of each link for all peer nodes in the cluster
#format: set-addr node-id link tag-name address
set-addr 1 link1 fe80::21a:64ff:fe92:1a92 
set-addr 1 link2 fe80::21a:64ff:fe92:1a93 
set-addr 2 link1 fe80::21a:64ff:fe92:1d70 
set-addr 2 link2 fe80::21a:64ff:fe92:1d71 
set-addr 3 link1 fe80::209:6bff:fe1b:1c94 
set-addr 3 link2 fe80::209:6bff:fe1b:1c95
