  • Cisco ASR 9000 Series Aggregation Services Routers

Known Affected Releases

4.3.2.BASE 5.1.0.BASE

Description (partial)

HSRP MGO slave groups send out router advertisement with interface MAC instead of vMAC address. Consequently the L2 network behind ASR9k does not learn the vMAC address and floods the frames destined to v6 HSRP group address.

When IPv6 HSRP have MGO enabled slave groups are impacted.
