Harry, Experts,
that makes a lot of sense: mss is an indirect indication of the mtu But what
about non TCP traffic, ICMP for example, 'path-mtu-discovery'
doesn't seem to work.

I guess that the effect of this command is to maintain a cache of all
the active connection and for each of them assign the discovered value
of the max mtu allowed accross the path.
At least the output of 'show system connections inet extensive'
doesn't show any trace of PMTU;

Hi,
I've been trying to get Path MTU Discovery working for M/J-series,
appreciate that the M-series requires vrf-mtu-check
