Hi, William

I think the broadcast will not be blocked, but the router with "no ip
directed broadbast" configured will replies other than all guys in this
subnet reply it.

So, I think

1) All guys in 192.168.2.0 will replies
2) Only R1 replies.

Please correct me if anybody find it wrong;

Thx,

Dear all,

    Can anyone kindly explain to me what actually does, if I configure "no
ip directed-broadcast" on an Interface? Thx a lot.

    For example:

    (192.168.1.0/24) - (E0) Router (E1) - (192.168.2.0/24)

    Suppose, if directed broadcast is enable on E0, but disabled on E1,
then:

    1) From 192.168.1.0, "ping 192.168.2.255" will be blocked?
    2) From 192.168.2.0, "ping 192.168.1.255" will be blocked?

Best Regards,
William Chen
