Juniper MX40 VRRP and cli question to

Hi, I've been working on Juniper equipment for over a year now, EX, QFX and SRX equipment mainly but we also have a pair of active/active MX40's at one of the data centres as well that i've only ever had to go on so far about 3 times (I've come from a heavy Cisco background), the weird thing i've spotted is that if you do a traceroute to our website that is hosted at that particular data centre then it goes to one of the outside physical interface IP's we have in the active/active pair always whereas it should be going to the VRRP IP, i have looked on both routers doing a "show int terse" and on the outside irb interfaces the public physical IP's are obviously there but on only ONE router is the VRRP VIP there to under the physical IP, so this obviously caused some suspicions...Doing a "show vrrp detail" everything looks alright for that group to be honest, master, backup, local and VIP are all what they should be...

We have other irb interfaces with VRRP as well and both routers have both their own physical IP's but also the VIP under them both to. Anybody any ideas as to what is going on here?

Oh and as a side note...The "show services sessions" command shows up absolutely nothing on the cli as well which i found odd. Anyone any ideas there to?

Thanks everyone
