VRRP runs between *two* routers. Aside from that, no specific problems
with M7i vs M10i (and why should there be? M7i and M10i are hardware
and software wise very much alike).

> 2) Should all routers have same Junos ?

Recommended but not strictly necessary.

> 3) VRRP messages can go between M7i and M10i with no problems ?


> 4) If VIP taken by M7i ? Does M10i  take the VIP in case of M7i failure ?

This has nothing to do with M7i/M10i, and everything to do with how
VRRP is configured. By default, a higher-priority backup router can
preempt a lower-priority master router, see
