I am having a EX2300 device wherein 'show ipv6 neighbor' entries are shown as Stale until some ping traffic comes in. Is it expected?
This is the configuration I have,
set groups ND system arp aging-timer 240
set groups ND interfaces xe-1/1/2 unit 0 family inet6 address 0001::1/64
set groups ND interfaces xe-1/1/3 unit 0 family inet6 address 1001::1/64
From the Spirent side, I started the devices, sent ND and I could see immediately neighbor table getting populated but state of the entry shown as STALE. However, if I send ping traffic from the device then I could see state changing to reacable. Even TRAFFIC from the port is not changing the state to REACHABLE, only ping from the device is changing the state to REACHABLE. Is this expected?
