Hi guys,
I'm using Quagga 1.0.20160315 and FreeVRRPd 1.1_1 on BSDRP 1.6.
Since BSDRP is basically a FreeBSD, I think to post it here.
I installed this BSDRP on a physical server, at its HDD, connected to a LAN testing network.
There is only 1 port connected from this BSDRP into the switch.
I run continuous ping to the VRRP Virtual IP (172.16.88.4) and the IP attached to its physical IP (172.16.88.5).
This is the only VRRP node in the network. I don't install another device that use VRRP.
This is a standalone VRRP node.
Problem: There is always (DUP!) ping replies when I ping the Virtual IP.
Workaround: restarting the freevrrpd service for every 10 minutes.
Symptom: The (DUP!) replies will start 15 minutes after the last freevrrpd service restarted.
I usually setup VRRP on Cisco or Juniper or Brocade, and got no (DUP!) problem.
I'm stuck.
I desperately need your help.
Have anyone going through this before?
If you have, what is the solution?
Below is the verbose informations you may require.
Thank you,
Ssoorruu
