Re: Configuration of T1 on Netvanta 3448

Jump to solution

Changing the IP address on the Adtran for Ethernet 0/1 to 11.205.205.5/31 still doesn't allow ping. I believe the Adtran engineer had already tried bridging the Adtran but still no ping. We may just look into redesigning the way we connect client side equipment since this seems to not want to work.

You can't route the same subnet on both sides of the link. Assign a different subnet to the ethernet of the Adtran than you have on the ethernet of the upstream, not just a different IP in the same subnet.

I have now been able to reproduce the issue with our once working router. I will try a few changes on the Adtran and hopefully have better results. Will update here once complete.

I was able to reproduce the issue on our Tiara router (bundle up but no routing). The config I yanked out from the Tiara is below. I don’t know of a way to add the VLAN ID to the 3200/3448 Adtran. On the 3200, when I assign the Ethernet port as a VLAN trunk it disables the ability to assign a static IP. The TEST is the bundle that is configured on our DS3 as well as the client side Tiara. It seems that without this VLAN ID/default route, the IP routing fails. Is there a way to replicate this configuration on AOS?

vlanfwd

  add  vlanid 41 TEST

  management

    vlanid 41

    default_route 11.205.205.200 TEST

    exit management

  exit vlanfwd

So I configured the interface eth 0/1 with 802.1q encapsulation, then created a sub interface eth 0/1.1. I then assigned the vlanid 41 to be the native vlanID for sub interface eth0/1.1. I then configured the PPP 1 interface with ip unnumbered eth0/1.1. The PPP 1 interface picks up the statically assigned IP from sub interface eth0/1.1 but still no routing. I even tried assigning a new IP 11.205.208.5/24 but still no success.
