Info
titleNote
  • EVPN feature is currently supported on X86 platforms only.
  • To enable a BGP node as a route reflector for EVPN, you need to configure both of the following two commands:

set protocols bgp [vrf <vrf-name>] neighbor <bgp-peer> route-reflector-client

set protocols bgp [vrf <vrf-name>] neighbor <bgp-peer> evpn route-reflector-client

  • The clear command (run clear mac address table all and run clear arp all) does not work for manually clearing the dynamic entries in the EVPN MAC address table or ARP address table. These entries can be aged and removed after the Linux kernel aging timer expires.

...

ARP/ND suppression can be enabled on L2 VNI and works only on ARP/ND broadcast messages in the corresponding VNI enabled with this function.

Remove EVPN Configuration

Warning:

To correctly remove EVPN configuration, the following deletion sequence needs to be followed.

  1. First, remove the data plane configuration, that is, VXLAN-related configuration, including commands under the following configuration node: set vxlans xxx.
  2. Then, remove the control plane configuration, that is, BGP and BGP EVPN related configurations, including commands under the following configuration node: set protocols bgp xxx.
  3. Last, delete VXLAN related L3 interface configuration, including the following commands:

          set l3-interface vlan-interface xxx

         set l3-interface routed-interface xxx

If you don’t follow this deletion order, the configuration in the kernel may still exist after the deletion operation, inconsistency in two systems (PICOS and kernel) may lead to unpredictable problems.
