I just tried the version 6.0rc6, the VPLS's tunnels are well established, but only 1472 or less bytes packets are allowed to pass, if I try with 1500 bytes packets, they don't ... this causes problems especially in TCP packets, the TCP bandwidth test is impossible! if I get back to 5.22 version, everything is fine again.

check mpls mtu and max l2mtu values on interfaces.

check mpls mtu and max l2mtu values on interfaces.

The whole MPLS cloud has 1516 as MPLS MTU.

RB1100AHx2
ROS: 5.19
Firmware: 2.39
ether6 L2MTU 1598 (to RB800)

to

RB800
ROS: 5.22
Firmware: 3.02
ether2 L2MTU 1600 (to RB1100AHx2)
WLAN L2MTU 2290 (to RB433AH)

to

RB433AH
(ROS: 5.22 OK - ROS: 6x not working)
Firmware: 3.02
WLAN L2MTU 2290 (to RB800)


What can be?


PD: there are no VLANs involved.

check mpls mtu and max l2mtu values on interfaces.

Any suggestions except this?
