Routers
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:
