[jens.hoffmann at ddkom.de]

Hi Hannes,

I'm using the same JUNOS 7.0R2.7 on each device (M7i, M10i, M5 and M10).

The end to end RTT is not conspicuous.

Model: m7i
JUNOS Base OS boot [7.0R2.7]
JUNOS Base OS Software Suite [7.0R2.7]
JUNOS Kernel Software Suite [7.0R2.7]
JUNOS Packet Forwarding Engine Support (M7i/M10i) [7.0R2.7]
JUNOS Routing Software Suite [7.0R2.7]
JUNOS Online Documentation [7.0R2.7]
JUNOS Crypto Software Suite [7.0R2.7]

Kind Regards
Jens
