Hi Obaid,

 

I think we do not require sending the PATH MTU to the original source at all. 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).

 

Thanks,

Vishwas

Hi

 

Can intermediate routers do Path MTU discovery or  the originator of packet will do it ONLY?

for e.g. In case of VPN; can router for encapsulation do PMTU and send the "PMTU - (size of Data used for encaspulation)" to Source so encapsulation wont fragment the packet?

 

Thanks
