Sean,

Yes, I am using irb interfaces.  Since they are not listed under the 
"site" stanza, I did not think the irb would make any difference. 
Obviously, I was mistaken.

Is there any way to force the failover mechanism to work when configured 
for irb?  Or is there a workaround to consider?

I am trying to terminate the "L3 side" of the VPLS instance with VRRP 
(defined in a VRF instance that include the same irb) on the MX routers 
that are configured to support a VPLS multihomed site.  Can I still do 
this, or does the irb have to be on a separate physical MX router?
