Hi,

I used to use extended ACL. And only permiting specified protocol can trigger dial-up. DNS, SNMP also can trigger dial-up.

Subject: Why does broadcast still trigger the call?

Hi guys,

When configuring DDR between 2 sites, I noticed that the broadcast still
triggered the call. The "show dialer" displayed: Dial reason: source:
x.x.x.x, destination: 255.255.255.255.

The interesting traffic was defined: dialer-group 1, dialer-list 1
protocol
ip permit
Also, I used the command "no ip directed-broadcast" and "no cdp enable"
at
both sides and no routing protocols running between two sides.

Anyone can tell me why broadcast packet still trigger the call and how
to
prevent this?

Thanks
Tran Tien Phong
