For example, with the following interfaces:
■ For first network interface
IP address=192.168.30.1, Broadcast address=192.168.30.255,
Netmask=255.255.255.0
■ For second network interface
IP address=192.168.31.1, Broadcast address=192.168.31.255,
Netmask=Mask:255.255.255.0
Configuring the broadcast address for LLT
Fornodes on different subnets,set the broadcastaddress in /etc/llttabdepending
on the subnet that the links are on.
An example of a typical /etc/llttab file when nodes are on different subnets. Note
the explicitly set broadcast address for each link.
# cat /etc/llttab
set-node nodexyz
set-cluster 100
link link1 udp - udp 50000 - 192.168.30.1 192.168.30.255
link link2 udp - udp 50001 - 192.168.31.1 192.168.31.255
