Hi all
I have some problem with gre tunnels. I need to fragment packages in tunnel. I
run gre between two jseries (junos 10.4R6) and lunch MPLS on it. The problem
looks like that packages with MTU above 1476 are not fragmented/reassembled and
are dropped.
interfaces gr-0/0/0
unit 10 {
clear-dont-fragment-bit;
description "Tulne to r1-lab";
tunnel {
source 10.200.0.1;
destination 10.200.0.2;
allow-fragmentation;
path-mtu-discovery;
}
family inet {
mtu 1500;
address 100.100.100.1/30;
}
family mpls {
}
}
Have someone have similar problem ? is there a simple way to fix this ?
Best Lukasz
