  • 1.  MAC-VRF type VLAN-bundle example config not working

    Posted 12-22-2024 19:39

    Hi everyone,

    I am trying to lab up MAC VRF  vlan bundle.  

    https://www.juniper.net/documentation/us/en/software/nce/evpn-vxlan-mac-vrf/EVPN_VxLAN_MAC-VRF.pdf

    Based on the above link,  MAC-VRF VLAN bundle can have multiple vlans ( bridge domains) but all tied to single VNI.

    I built the following config:


    set routing-instances EVI-BUNDLE instance-type mac-vrf
    set routing-instances EVI-BUNDLE protocols evpn encapsulation vxlan
    set routing-instances EVI-BUNDLE protocols evpn extended-vni-list 1000
    set routing-instances EVI-BUNDLE vtep-source-interface lo0.0
    set routing-instances EVI-BUNDLE service-type vlan-bundle
    set routing-instances EVI-BUNDLE interface ge-0/0/3.0
    set routing-instances EVI-BUNDLE interface ge-0/0/4.0
    set routing-instances EVI-BUNDLE route-distinguisher 3.3.3.3:1
    set routing-instances EVI-BUNDLE vrf-target target:1:1

    set routing-instances EVI-BUNDLE vlans v100 vlan-id 100
    set routing-instances EVI-BUNDLE vlans v100 vxlan vni 1000
    set routing-instances EVI-BUNDLE vlans v200 vlan-id 200
    set routing-instances EVI-BUNDLE vlans v200 vxlan vni 1000

    However when I  try to commit, I  am getting following error:

    Model: ex9214
    Junos: 23.2R1.14

    What am I missing?

    Apparently, JUNOS is complaining we can not have multiple VLANS tied to single VNI but that isn't what MAC-VRF  VLAN bundle supposed to be?

    Much appreciated!!

    Hi,

    I have only briefly deployed the MAC-VRF service-type VLAN-Based and VLAN-Aware for a lab test once, but I think the service-type VLAN-Bundle is for Q-in-Q type scenarios for "dot1q-tunneling".

    The difference being be that any incoming VLAN-tag would not be popped, and with VLAN-Based they would be popped. It would be ok to use "vlan-id-list" on the interface I assume.

    If you really want multiple VLANs in one VPN then you'd need service-type VLAN-Aware.

    Otherwise, you'd have to create 2x a separate VPN with service-type VLAN-Based and that probably forces you to a SP-style configuration at interface level.

    Thanks,

    I was just trying to learn this particular mac-vrf so when I see in production network I know how it works and how I can troubleshoot. So basically looking for any  working example of this mac-vrf type.
