VXLAN config issues

Sat Feb 15, 2020 3:13 am

Problem: cannot ping through vxlan interfaces

Topology: hex-s — crs328 — rb4011

I upgraded everything to v7b5 and tried setting up the vxlan interfaces on the hex and 4011, the crs328 is just a switch. The Vxlan interfaces show as online and I can torch the vxlan interface and see the incoming and outgoing icmp traffic, but the pings are still timing out.

Do I need any settings on the crs328?
Where’s the wiki page for vxlan?

Thanks!

Here is an example working lab in EVE-NG between 3 routers and 3 linux servers from an article I wrote:

Configs are in the link here:

Awesome, thanks! I'll give that a try. Do you think fragmenting everything is ok, or do you make the l3 mtu high enough to not fragment?

In the lab, I just lowered the VxLAN MTU to 1400 because it was quick and easy. But in production, I would raise the IP MTU of the routed network to something larger like 9000 so that 1500 byte frames can pass without issue.
