Customer uses AR201 with V2R6 software.
Main idea, because of narrow
channel between HUB and remote client, client can’t send copy of data for each
server in realtime. So, they used
directed broadcast, in order only one copy of data will be sent via WAN
After checking Product
documentation for AR found command “ip forward-broadcast”. But it was not
working as expected. AR didn’t send out unicast broadcast packet.
Step 1 :
acl number 3000
rule 5 permit ip destination 192.168.10.0 0.0.0.255
ip forward-broadcast acl 3000
anti-attack abnormal disable
source of direct-broadcast traffic (192.168.1.201) -
fe6(192.168.1.254) AR201 fe0 (192.168.100.253) - destination (192.168.100.105)
Capture from input AR interface fe6
Capture from output AR interface
fe0- no output
This feature of Forwarding Directed
Broadcast Packets cannot be supported by the current AR. Product manual about ip forward-broadcast
Directed Broadcast is VRP platform features, non-AR product features,
Product manual is
copy over from VRP platform, not cropped. At fresh version of product
documentation it will be fixed.
Use another way to
save narrow WAN link bandwidth.
