All platforms

Also try to do ping to a multicast group address. The bundle configuration in tacppd.conf file should be looking like:

access 4 

 permit ^239.1.1.1$ 

exit

listener 11000 

 type bundle 

 maxconnect 10 

 acl 4 

exit

bundle 239.1.1.1:11000 

 description 'tacppd multicast group' 

 cryptokey key1 

 ttl 1 

exit

The ttl=1 only if all nodes connected to one LAN. If you have routers and other network between nodes, set ttl to more. Also set routers for multicast routing.
