Not getting decapsulated VXLAN traffic on second interface
by TC123 from LinuxQuestions.org on (#5SSKD)
I'm running an Ubuntu 18.04 system in AWS. It has 2 interfaces configured (ens3 and ens4). ens3 is the primary interface. ens4 is getting VXLAN traffic. I've verified that the traffic is coming in on ens4 with a packet capture.
I setup a VXLAN interface by running these 2 commands:
$ ip link add vxlan1 type vxlan id 1 dev ens4 dstport 4789
$ ip link set vxlan1 up promisc on multicast on
I expected to see traffic on vxlan1, but nothing appears there at all :(
As a sanity check, I setup a second system, but with only 1 interface (ens3). I ran the same commands as above, adjusting the dev to ens3. There when I run a packet capture for the same VXLAN traffic I see it on vxlan1.
What am I missing when setting up on a system with 2 interfaces?
Thanks!
