VxLAN MTU settings
Posted: Wed Jan 17, 2024 9:00 pm
I have created a VxLAN between an RB2004 and RB2116.
The Network has 1500 L3 MTU and 1584 L2 MTU between the two routers.
For the VxLAN I set the MTU to 1500, and it shows the Actual MTU as 1500 and the L2 MTU as 65535.
If I try to ping through the VxLAN with DF enabled, the largest packet I can pass is 1450 bytes.
I also have VPLS Tunnel between the same routers which is able to pass 1500 byte packets without fragmentation.
Is it possible to have a Full 1500 byte packet pass through a VxLAN?
If I set up a PPPoE Server on the VxLAN using 1480 MTU would I be able to have 1480 MTU on my PPPoE Connection without fragmentation since PPPoE is a Layer 2 connection, or will there be fragmentation happening?
