[j-nsp] Overlay physical interfaces and Overlay next-hop

[Phan Thanh Tung (FPT Smart Cloud)]

Junos allows to re-allocate the maximum number of physical interfaces and the maximum number of next hops reserved for use in an Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) overlay network.

[edit forwarding-options]
vxlan-routing {
      interface-num integer;
      next-hop integer;
      overlay-ecmp;
}

I don't know how to determine how many overlay physical interfaces and overlay next-hop have been used.

Hope to hear from someone experienced in determining these parameters when controlling the scale of EVPN-VXLAN fabric. Many thanks for your help in advance.

Thanks and Best Regards,
