I agree with Itojun According to the text, this is configurable value with a default of 1280. This makes it no different then any other IPv6 link. That is simplest case and lets keep it this way. -vlad itojun@iijlab.net wrote:
To maximize efficiency and minimize IPv4 fragmentation for the predominant deployment case, the ISATAP interface MTU, or "LinkMTU" (see: [RFC2461], Section 6.3.2), SHOULD be set to no more than 1380 bytes (1400 minus 20 bytes for IPv4 encapsulation)." Can we have something similar for mech-v2?I don't personally have a problem with raising the tunnel MTU in mech-v2from 1280 to 1380.What do others in the WG think?keep it to 1280. it is the simplest value. the most important point in non-dynamic tunnel mode is simplicity. itojun
