How to forward ethernet broadcasts to an ISDN PRI? |
|
|
We use a Cisco 2621 and a NM-2CE1B (double ISDN PRI). 60 window-pc's
can
dial in, using one B-channel each.
for our application we need to forward broadcast packets from the
ethernet interface
to all the B-channels.
I tried this (part of the config)
'
!
interface FastEthernet0/1
ip helper-address 192.168.100.255
!
interface Dialer1
ip address 192.168.100.1 255.255.255.0
ip directed-broadcast
'
This doesn't seem to work. Using a the 'ip helper-address' entry for
each of the B-channels does but, is there any other way to forward the
broadcasted packets?, as using many 'ip helper-address' entries, makes
the router unusable slow...
TIA, Marcel. |
