Broadcast Domain Testing
Hello,
So I am having an issue with a broadcast domain. I have the gre tap tunnel set up but the additional entries from the other side do not show up on the ARP table. I cannot use ping or ping variations due to ICMP not being allowed through the firewall.
I need to be able to actively prove that it exists. If anyone has any ideas on how to dynamically add the neighbors to the ARP table (can't be static) or something else that I missed that would be great
P.S. Never posted here before so if this is too much like asking for an answer let me know so I can delete it
