bridge-list and dialer-lists

Hi all,

I have applied on an dialer interface both an output bridge list (with the command bridge-group output-address-list) and a dialer list

My question is: if a bridging traffic is filtered (denyed) by the bridge-list, is this traffic able to trigger the ISDN call when valued as "interesting" because permitted by the dialer-list ?

Thanks all for your support

Re: bridge-list and dialer-lists

Hello,

I have tested this at home, but the bridge list did not seem to have any influence on the interesting traffic triggering the ISDN connection. To be honest I am not sure if the configuration of my access list 700 was blocking anything though. Can you post the config of your ISDN router ? I will copy it to my system at home and test.

Regards,

Re: bridge-list and dialer-lists

Hi GP, thanks for the answer

Here is the relevant config

interface BRI0/0

ip address 192.168.1.6 255.255.255.252

no ip directed-broadcast

encapsulation ppp

dialer idle-timeout 500

dialer string

dialer-group 1

isdn switch-type basic-net3

no fair-queue

ppp authentication chap

ppp multilink

bridge-group 1

bridge-group 1 output-address-list 701

!

!

ip route 10.1.1.0 255.255.255.0 Dialer1

!

!

access-list 701 permit 0060.B0A4.53AF 0000.0000.0000 (Dest-MAC-NIC-EMOS)

!

dialer-list 1 protocol bridge permit

dialer-list 1 protocol ip permit

bridge 1 protocol ieee

!

As you can see the applied dialer list let pass all the bridged traffic, but I have tested that at the end the traffic able to trigger the ISDN call is only the one filtered by the output bridge list (having as destination MAC a particular MAC address)

should't the bridge lists as the access lists act before the packet is put in the interface queue and thus before is able to trigger an ISDN call ?
