Specifying a TTL Value for a Rebroadcast Packet
The TTL value restricts the number of routers a rebroadcast packet can traverse.
To prevent NetBIOS broadcast packets from traversing the network indefinitely,
set the parameter to a minimal value.
By default, NetBIOS sets the TTL value in each packet to 5. You can use Site
Manager to set a TTL value from 1 to 255.
Enabling the Insertion of Record Route Option
The Insertion of Record Route option prevents rebroadcast packets from looping
forever by allowing the NetBIOS entity in the router to determine whether it has
received this packet before on this interface. If so, the router drops it.
