Hello all,
I've looked around and there seem to be very little info when configuring this, but apologies if I missed this, and this is also my first post so my bad if this is explained poorly but my goal is this:
- bt adsl terminating to 4321 with NIM-VAB-A, no ppp from the ISR but passing the l2 traffic straight to the MX on the gigabit port for PPP from the MX. (not sure if this can be done but worth a try)
Problem I have encountered is that there seem to not be any traffic passing, and the config of the ISR is simply :
controller vdsl I've left in mode auto (I did try also VDSL2 to force for g.993.2)
interface ATM0/1/0
no ip address
atm oversubscribe factor 2
no atm enable-ilmi-trap
and then:
interface ATM0/1/0.1 point-to-point
no atm enable-ilmi-trap
pvc 0/38
encapsulation aal5mux ppp dialer
traditionally to establish ppp straight from the ISR the config would be the same except that I add the dialer config, so under "encapsulation" I would have:
dialer pool-member 1
and then in the dialer pool define the parameter similar to this:
interface Dialer0
ip address negotiated
ip nbar protocol-discovery
ip nat outside
encapsulation ppp
dialer pool 1
dialer-group 1
no cdp enable
ppp chap hostname bthomehub@btinternet.com
ppp ipcp dns request
ppp ipcp wins accept
ppp ipcp route default
But I noticed since BT upgraded the line to vdsl (G_993_2_ANNEX_B), that neither configs work. And for bridging this is the configs used under the interfaces:
interface GigabitEthernet0/0/1
no ip address
negotiation auto
service instance 1 ethernet
encapsulation dot1q 1
creating the bridge interface:
interface BDI 1
description bridge bt to mx
encapsulation dot1q 1
no shut
And then added also the ethernet interface to the same bridge with same config, but instead of using the dialer interface since its vdsl, it uses the ethernet interface? Not sure which is correct as there is quite allot of secrecy around the adsl structure, and would be grateful is someone could break it down because as far as I know, when using adsl, the ISR uses the controller for choosing the ADSL mode, the atm interface for the modulation and encapsulation settings, and the dialer interface for the ppp settings etc... when setting to vdsl mode does this remove the use of the atm interface and dialer and just uses the ethernet?
post with the complete config will follow but would be great to get some input on this as it would be great to see what engineers do out there :)
