Description: The tunnel MTU.
What is usdIpTunnelMtu?
This sets the maximum transmission unit, in bytes, for this tunnel interface. Admins tune it to avoid fragmentation of tunneled traffic, keeping it small enough to account for the tunnel encapsulation overhead added on top of the payload. An admin might lower this from the default of 10240 to 1400 to leave headroom for GRE encapsulation overhead on a path with a 1500-byte physical MTU.
