    Posted 13 days ago

    Hi dear community,

    I am facing an issue with the following setup :

    Ping is not OK for the BGP EVPN VPWS Service (Vlan / EVC 20).

    Here is the configuration of the involed PE :

    Cisco PE ISR1111:

     

    interface GigabitEthernet0/0/1
     no ip address
     negotiation auto
     !
     service instance 20 ethernet
      encapsulation dot1q 20
    !
    l2vpn evpn instance 20 point-to-point
     route-target export 65003:20
     route-target import 65003:20
     no auto-route-target
     vpws context EVPN-12120
      service target 121201 source 121202
      member GigabitEthernet0/0/1 service-instance 20
    !
    router bgp 65003
     bgp router-id 10.0.0.21
     bgp log-neighbor-changes
     neighbor 10.0.0.1 remote-as 65003
     neighbor 10.0.0.1 update-source Loopback0
     !
     address-family l2vpn evpn
      neighbor 10.0.0.1 activate
      neighbor 10.0.0.1 send-community both
      neighbor 10.0.0.1 soft-reconfiguration inbound
     exit-address-family

     

    JUNIPER PE SRX300:

     

    et interfaces ge-0/0/5 unit 20 description "vlan l2vpn-test-Evpn-vpws_Bgp_Signaling"
    set interfaces ge-0/0/5 unit 20 encapsulation vlan-ccc
    set interfaces ge-0/0/5 unit 20 vlan-id 20
    !

    set routing-instances evpn-12120 protocols evpn control-word

    set routing-instances evpn-12120 vrf-import L2Vpn-evpn-12120-Import
    set routing-instances evpn-12120 vrf-export L2Vpn-evpn-12120-Export
    !
    set protocols bgp group Bgp-Evpn-Signaling type internal
    set protocols bgp group Bgp-Evpn-Signaling local-address 10.0.0.1
    set protocols bgp group Bgp-Evpn-Signaling family evpn signaling
    set protocols bgp group Bgp-Evpn-Signaling neighbor 10.0.0.21

     

     I can see some drops on the RX side of the Cisco PE :

    VC is up but a ping from station A to B does not work.

     

    PING 192.168.20.2 (192.168.20.2) 56(84) bytes of data.
    From 192.168.20.1 icmp_seq=1 Destination Host Unreachable
    From 192.168.20.1 icmp_seq=2 Destination Host Unreachable
    From 192.168.20.1 icmp_seq=3 Destination Host Unreachable
    From 192.168.20.1 icmp_seq=5 Destination Host Unreachable
    From 192.168.20.1 icmp_seq=8 Destination Host Unreachable
    From 192.168.20.1 icmp_seq=11 Destination Host Unreachable

     A packet capture on interface Gi0/0/0 on the Cisco PE shows the packet from Host A arriving at the Cisco PE (ARP request) but it does not exit the router on interface Gi0/0/1 towards Host B.

    Any idea folks ?

    Thanks in advance for your kind help.

    Best Regards,
