Can someone please explain in detail why we need to setup static arp entry on each MC-LAG peer. This is mentioned below in Juniper Documenttation
Its under topic Virtual Router Redundancy Protocol (VRRP) over IRB and MAC Address Synchronization
If you are using the VRRP over IRB method to enable Layer 3 functionality, you must configure static ARP entries for the IRB interface of the remote MC-LAG peer to allow routing protocols to run over the IRB interfaces.
This step is required so you can issue the ping command to reach both the physical IP addresses and virtual IP addresses of the MC-LAG peers.
But why this thing wont work without using static ARP? Can someone please explain this.
