  • 1.  [MX][MPLS] How to bind a bridge-domain on a MPLS VRF instance

    Posted 07-01-2013 03:06

    Hello there,

     

    The goal is to have a broadcast domain available (tagged or not) on several interfaces of the MX (MX80 in here). This domain (the several interfaces then) should be bind to a L3VPN (VRF instance I assume).

     

    Is it possible ?

     

    If Yes how? because it seems I can't add a bridge-domain in a vrf routing-instance type. I also found some virtual-switch implementation but only for VPLS whereas i'm looking for a l3vpn in my case.

    If you know a documentation where the solution is, please link me, didn't find it so far :).

     

    Thank you in advance for your help.

    You can get an irb interface doing the job

    I only used irb interfaces on bridge domain then i don't see how to implement it. Could you be more specific ?

    Hello there,

    The sequence of operation is as follows:

    1/ confiure VRF(s)

    2/ configure bridge-domain(s)/BD

    3/ configure physical fe-|ge-|xe-|ae- interface with "encapsulation <extended-vlan-bridge|ethernet-bridge|flexible-ethernet-services>" 

    4/ if using "flexible-ethernet-services", configure logical fe-|ge-|xe-|ae- interface unit(s) with "encapsulation vlan-bridge" , vlan-id and "family bridge"

    5/ if using "encapsulation ethernet-bridge" configure logical fe-|ge-|xe-|ae- interface unit 0 with "family bridge"

    6/ else configure logical fe-|ge-|xe-|ae- interface unit(s) with vlan-id and "family bridge"

    7/ add logical fe-|ge-|xe-|ae- interface unit(s) already configured with "family bridge" in step 4-6 into BD(s)

    8/ add IRB unit(s) into BD(s) using "set bridge-domain <BDname> routing-interface irb.<unit>" knob

    9/ add "family inet address <IPv4 address/masklen>" to IRB interface unit(s) 

    10/ add IRB unit(s) into chosen VRF(s)

    HTH

    Thanks
    Alex

    Seems OK thanks!

    I've tried to add the bridge domain instead of the irb in the VRF. That was my mistake as I thought the IRB only in the VRF was wrong.

     

    Many thanks for this detailed solution 🙂
