Using the UDP layer for LLT

	UDP
Node0	Node1
	UDP Endpoint eth1;
	UDP Port = 50001;
	IP = 192.1.3.1;
	Link Tag = link2
	eth1;
	192.1.3.2;
	Link Tag = link2

UDP Endpoint eth2; UDP Port = 50000; IP = 192.1.2.1; Link Tag = link1

eth2;

192.1.2.2;

Link Tag = link1

The configuration that the /etc/llttab file for Node 0 represents has directly attached crossover links. It might also have the links that are connected through a hub or switch. These links do not cross routers.

LLT broadcasts requests peer nodes to discover their addresses. So the addresses of peer nodes do not need to be specified in the /etc/llttab file using the set-addrcommand. For direct attached links, you do need to set the broadcast address of the links in the /etc/llttab file. Verify that the IP addresses and broadcast addresses are set correctly by using the ifconfig -acommand.

set-node Node0 set-cluster 1 #configure Links

#link tag-name device node-range link-type udp port MTU \ IP-address bcast-address

link link1 udp - udp 50000 - 192.1.2.1 192.1.2.255 link link2 udp - udp 50001 - 192.1.3.1 192.1.3.255

The file for Node 1 resembles:

set-node Node1 set-cluster 1 #configure Links

#link tag-name device node-range link-type udp port MTU \ IP-address bcast-address
