Re: PMTU and Broken Servers

Hello Leo,
Could you define newer? My limited testing with 12.0S and 12.2something
shows both returing MTU can't be set on a tunnel interface.
concrete version number: 12.0(17)ST5. Just tried on a test 7200 with that code.

7204-R3(config-if)#mtu 1500
% Interface Tunnel1 does not support adjustable maximum datagram size

7204-R3(config-if)#ip mtu 1500
7204-R3(config-if)#


And from a tcpdump-ed ping I'm convinced it works :-)


Regards, Marc

Works on most newer IOS:es.
