Cisco IOS Router an Telekom Annex J ADSL BNG

Um einen Cisco IOS Router an einem Telekom Annex J ADSL im neuen BNG betreiben zu können ist ähnlich wie beim VDSL auf dem Ethernet auf dem ATM Interface ein entsprechender VLAN Tag nötig.

Die Konfiguration sieht wie folgt aus:

test-router#sh run int atm0/0/0
Building configuration…

Current configuration : 178 bytes
!
interface ATM0/0/0
description — WAN —
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
atm vc-per-vp 64
no atm ilmi-keepalive
end

test-router#sh run int atm0/0/0.7
Building configuration…

Current configuration : 114 bytes
!
interface ATM0/0/0.7 point-to-point
pvc 1/32
bridge-dot1q encap 7
pppoe-client dial-pool-number 1
!
End

Die Nutzung des ATM Sub-Interfaces ist zwingend erfoderlich, da der Befehl bridge-dot1q encap 7 im ATM Interface nach dem Reboot verschwindet. Erst im Subinterface ist er Rebootfest.

Getestet auf dem IOS 15.5(3)M6 und der Modemfirmware VA_A_39m_B_38h3_24h_o.bin.
