Re: [ns] Disabling ARP protocol for MAC evaluation

first you need to get a tcl reference for the arp-table: e.g. ($val(nn) = number of nodes in simulation) for {set i 0} {$i $val(nn) } { incr i } { set ll($i) [$node_($i) set ll_(0)] set arp($i) [$ll($i) get-arptable] } then you can put entries in the arp-table.
