[j-nsp] srx cluster - control and data link throuigh cisco

[Payam Chychi]

I 2nd this, check your mtu settings end to end, keep in mind the differences between cisco and juniper when it comes to calculating lowest required mtu value   

Mismatch mtu tends to have some very odd behaviour on protocols

There is a required frame MTU that must be supported across the network for connectivity through intermediate switches to work / be supported. Also if i'm not mistaken by default the control plane traffic is tagged with VLAN 4090, however in later versions of code that default behavior may have changed, and I think the VLAN ID it uses is now configurable.
