TCL MTU Discovery

[Cory Anderson]

Hi All,

I'm looking for a scalable solution to find the MTU of a path between tunnel endpoints and configuring the Tunnel IP MTU and TCP MSS accordingly. I can use the extended ping with df-bit and sweeping in size, but I'm hoping to leverage TCL so I can push this for multiple tunnels/devices at a time.

Any ideas?

Thanks,

Cory
