cannot ping between irb on the same subnet

  • 1.  cannot ping between irb on the same subnet

    Hi,

    I have setup 2 vMX as leaves (no spine at all) and configured them with routing instance type mac-vrf. I added the interface routing with irb. But I cannot ping between the irb on the same VLAN and VNI. Is there any mis-configuration on my setup?

    vMX1:

    set interfaces irb unit 100 family inet address 192.168.100.1/24

    set routing-instances v1100 instance-type mac-vrf
    set routing-instances v1100 protocols evpn encapsulation vxlan
    set routing-instances v1100 protocols evpn default-gateway no-gateway-community
    set routing-instances v1100 protocols evpn extended-vni-list 1100
    set routing-instances v1100 protocols evpn vni-options vni 1100 vrf-target target:100:100
    set routing-instances v1100 vtep-source-interface lo0.0
    set routing-instances v1100 bridge-domains v100 vlan-id 100
    set routing-instances v1100 bridge-domains v100 routing-interface irb.100
    set routing-instances v1100 bridge-domains v100 vxlan vni 1100
    set routing-instances v1100 service-type vlan-aware
    set routing-instances v1100 route-distinguisher 10.100.100.1:1
    set routing-instances v1100 vrf-target target:65000:1
    set routing-instances v1100 vrf-target auto

    vMX2:

    set interfaces irb unit 100 family inet address 192.168.100.10/24

    set routing-instances v1100 instance-type mac-vrf
    set routing-instances v1100 protocols evpn encapsulation vxlan
    set routing-instances v1100 protocols evpn default-gateway no-gateway-community
    set routing-instances v1100 protocols evpn extended-vni-list 1100
    set routing-instances v1100 protocols evpn vni-options vni 1100 vrf-target target:100:100
    set routing-instances v1100 vtep-source-interface lo0.0
    set routing-instances v1100 bridge-domains v100 vlan-id 100
    set routing-instances v1100 bridge-domains v100 routing-interface irb.100
    set routing-instances v1100 bridge-domains v100 vxlan vni 1100
    set routing-instances v1100 service-type vlan-aware
    set routing-instances v1100 route-distinguisher 10.100.100.2:1
    set routing-instances v1100 vrf-target target:65000:1
    set routing-instances v1100 vrf-target auto

    Thank you.
