[j-nsp] Switch mesh / VRRP question

[Jonathan Brashear]

In my experience, Juniper doesn't allow the same subnet to be assigned
to multiple _physical_ interfaces.

Hi all,

I'm having trouble figuring out how to use VRRP with two routers fully
meshed to two switches.

To achieve this, is it possible to have two interfaces on the same
router with virtual IPs on the same subnet?  I'm thinking it would look
like the config below but I am not sure if this would work.

Regards,

Alex
