Hey Guys,

We are migrating some NE to new MX-5 LER.  I have started with moving mgmt
to an IRB,  IRB is in the bridge domain and in the routing instance.  When
cut over about half the NE are no longer accessible.

When the NE are cut back to old default GW (resides on a c7609 within a RI)
and pass through the MX as L2 with in the bridge domain  only it all works
fine.  Only when cutover to the NE PE does it break on some devices.

All routing appears to be working as some NE with in the subnet
are accessible.  not sure why other are not?  any idea would be appreciated.

    family inet {

    }
}

}
