Recently I realized that a llt interface in a cluster is not working because the nodes are in different vlans (the interface uses broadcast conf):

There is a sample llttab file for LLT over UDP at https://www-secure.symantec.com/connect/forums/if-llt-could-be-configured-over-udp-nat#comment-75424....
Note also, you can't mix LLT over UDP and LLT over Ethernet - see https://www-secure.symantec.com/connect/forums/how-configure-llt-over-udp-when-you-have-more-1-node-...
I have just chosen 3 UDP ports at random - 50100, 50101, 50102.

Very helpful Mike.
So, are the commands I executed correct?? I mean, does the command "lltconfig -l -t eth0 -d eth0 -b udp -I 10.92.5.134 -B 10.93.146.124" translate to
The main doubt I have is about the -B param...

The VCS install guide says:
Use LLT over UDP in the following situations:
■ LLT must be used over WANs■ When hardware, such as blade servers, do not support LLT over Ethernet
LLT over UDP is slower than LLT over Ethernet. Use LLT over UDP only when thehardware configuration makes it necessary.
The set-addr command in the /etc/llttab file is required when the broadcastfeature of LLT is disabled, such as when LLT must cross IP routers.

If i define the -B as the actual broadcast address, It doest work:
