Hi, A few more minor things to add: -
1. If the packet is to be sent over the tunnel and needs to be fragmented we could send the Type=2, Code=0 to the source. 2. One of the documents I found was http://www.ietf.org/internet-drafts/draft-savola-mtufrag-network-tunneling-05.txt . You could look at it.

The original source when doing a Path MTU would use the tunnel and the PMTU would correctly work (the tunnel would be another link in the path).
