I would like to tunnel IP packets over an IP network, and this IP network has 1500 MTU (regular ethernet MTU). In the cisco tunnel (and most others) the tunnel MTU ends up being 1450-something bytes. This is not acceptable, I need something that is able to split the packet up into two packets so that the tunnel MTU will be 1500.
Why is it "not acceptable"? Can you configure a Path MTU of 1450 to avoid fragmenting, or run Path MTU Discovery? -- Valdis Kletnieks Operating Systems Analyst Virginia Tech
