Point-to-Point T1s with 2 remote offices

[Anonymous]

I am new to setting up T1 point-to-point connections. I was trying to setup a Netvanta 3200 3rd Gen with a dual T1 card in bridge mode to connect two other Netvanta 3200 3rd Gen with the single T1 card in them. I can get one or the other to work but not all of them at the same time. Please help me with the configuration of this device. Scenario is a main location (A) with two remote offices (B & C). All need to be on the same network. Location A has a Netvanta 3200 3rd Gen with a dual T1 card and Location B & C both have a Netvanta 3200 3rd Gen with the single T1 card. We have a T1 that runs from location A to B and location A to C.

Thank you for posting your question, and supplying the configuration.  For further reference and advanced bridging configuration examples you can view the "Configuring Bridging in AOS" document.

Configuring IRB in AOS firmware release after 17.07.00 requires the completion of the following tasks:

  • Enabling IRB

  • Configuring the bridge group

  • Configuring the BVI interface

  • Removing IP addresses from all interfaces that will be added to the bridge group

  • Assigning interfaces to the bridge group

You have accomplished most of these tasks in the first configuration you posted above, but there are a few things you will need to add or change.

1. Enable IP routing with the ip routing command.
2. Enable IRB using the bridge irb command from the Global Configuration mode prompt. Enter the command as follows: (config)#bridge irb
3. Enter the BVI interface configuration mode using the interface bvi <number> command from the Global Configuration mode prompt. The <number> parameter is the bridge group number, and it must match the bridge group number you are working with. The number that you specify causes the BVI interface to be associated with all physical interfaces assigned to that bridge group. To enter the BVI Interface Configuration mode, enter the command as follows:  (config)#interface bvi 1

When you have completed this, your configuration should look similar to the output below:

ip routing

!

bridge irb

!

bridge 1 protocol ieee

!

interface eth 0/1

  bridge-group 1

  bridge-group 1 vlan-transparent

  no ip address

  no shutdown

!

interface t1 1/1

  clock source internal

  tdm-group 1 timeslots 1-24 speed 64

  no shutdown

!

interface ppp 1

  bridge-group 1

  bridge-group 1 vlan-transparent

  no ip address

  ppp bcp tagged-frame

  mtu 1524

  no shutdown

cross-connect 1 t1 1/1 1 ppp 1

!

interface bvi 1

  ip address X.X.X.X Y.Y.Y.Y (If you enter an IP address and subnet mask for management)

  no shutdown

I hope that makes sense, but please, do not hesitate to reply to this post with any questions or additional information, I will be happy to help in any way I can.

That worked for me. Thank you so much!

How do you set this up so that down stream devices can be managed with management vlan?

Thank you for asking this question in the support community.  If I understand the question properly, by default, downstream devices should be able to be managed in this configuration, because the ADTRAN is going to pass this traffic through.  Please, feel free to expand on this question, with additional information, and I will be happy to help in any way I can.
