Cisco NCS 5500 and HSRP

Hi,

I'm deploying NCS 55A2 pairs in my network and am having issues with HSRP. Running IOS-XR 6.6.3. HSRP VIP is pingable upstream from NCS boxes but not downstream on 802.1q subinterfaces interfaces. HSRP and ARP tables on downstream devices look good but you cannot use HSRP address as gateway. Addresses on subinterfaces work as advertised.

Have any of you guys had issues with HSRP not working correctly on NCS? Thanks in advance.

Addresses on subinterfaces are .42 and .43.
