Cause
On EX9200 switches, if an IRB logical interface is congured on an EX9200-6QS line card as part of a
VLAN, any device that is connected through that interface is unable to route trac outside of the
subnet because the EX9200-6QS line card drops all ARP requests. This happens because even though
the minimum Junos OS release that supports the EX9200-6QS line card is Junos OS Release 14.2R1,
this release does not support a conguraon that includes an IRB logical interface congured on an
EX9200-6QS line card as part of a VLAN.
Soluon
Upgrade Junos OS to the release specied in TSB16659.
