Helllo,
I'm configuring my ASR 1000 router with an Ethernet over GRE tunnel. Anytime I sent the Ethernet over GRE messages to the tunnel, the ASR router didn't recognize the messages were sent over the GRE tunnel. The ASR said that the messages were received on the LAN management interface, which was not what I intended. I'm wondering if the messages were not encapsulated correctly or I need to configure more on the ASR. I attached an ARP over GRE message capture.
Here is the router's log
*Jun 4 13:48:00.371: IP ARP: rcvd req src 10.14.18.1 0025.642c.4441, dst 10.14.18.152 GigabitEthernet0
*Jun 4 13:48:01.404: IP ARP: rcvd req src 10.14.18.1 0025.642c.4441, dst 10.14.18.152 GigabitEthernet0
