Need assistance for EVPN/MPLS IRB configuration

  • 1.  Need assistance for EVPN/MPLS IRB configuration

    Posted 07-18-2021 19:43
    I have the following configuration
    set interfaces irb unit 110 family inet address 192.168.1.254/24
    set protocols ospf area 0.0.0.0 interface irb.110 passive
    
    set routing-instances blue-evpn instance-type evpn
    set routing-instances blue-evpn vlan-id 110
    set routing-instances blue-evpn interface ge-0/0/3.110
    set routing-instances blue-evpn interface ge-0/0/5.110
    set routing-instances blue-evpn routing-interface irb.110
    set routing-instances blue-evpn vrf-target target:110:110
    set routing-instances blue-evpn protocols evpn

    I am not sure whether the issue is related to the image I used. I tested the same configuration on version 18.2, it seems working. the original image I used is version 14.

    thanks a lot !!

    ah yes 14 is very old code now. I'm glad you have it working now :)

    As version 14 uses less resources, sometimes I still use it. But  some time it gives me some troubles.  I have version 18.2 vMX, but I can't run many nodes even my server has 192G RAM.  Thinking of getting a nicer server. :)
