Question: 1
A vPC Type-1 inconsistency between two vPC peers in a VXLAN EVPN setup is discovered. Which
two actions need to be attempted to resolve the issue? (Choose two.)
A. Configure the NVE interfaces to be Up on both switches.
B. Set a different distributed gateway virtual MAC address.
C. Set a different secondary IP addresses on NVE source-interface.
D. Configure the same VNI to multicast group mapping.
E. Set a different primary IP addresses on NVE source-interface.
Answer: A, D
Explanation:
Configure the NVE interfaces to be Up on both switches; Configure the same VNI to multicast
group mapping is the valid corrective action because the failure described is a protocol or fabric
state problem, not a generic connectivity issue. For vPC, VXLAN, EVPN, NVE, VNI, Cisco
troubleshooting expects the engineer to compare both endpoints of the relationship: vPC peers
must agree on consistency parameters, HSRP peers must exchange hellos in the same VLAN and
version context, OSPF/BGP peers must match the attributes required for stable adjacency, and
VXLAN EVPN must advertise the correct host or prefix information. The selected option restores
that required state. The other options either operate on the wrong layer, change a value that is
not used to form the relationship, or would make the peer relationship less deterministic. A
clean validation is to inspect the control-plane table first, then verify the forwarding table, and
finally test end-to-end traffic. This is the Cisco-preferred approach because it avoids random
changes and confirms that the fabric is forwarding based on correct protocol state.
Question: 2
A mission-critical server is connected to site A. Connectivity to this server is lost from site B
because the MAC route is missing in the OTV VDC of the Nexus 7000 in site B due to MAC aging.
Which action allows the flooding of the unknown unicast MAC on the Nexus 7000 in the OTV
VDC?
A. Use route-map to advertise this MAC statically and redistribute with ISIS.
B. Unknown unicast flooding is not allowed.
C. Use the otv flood mac <> command to selectively flood traffic for a given MAC.
D. Use the otv isis bfd <> command to configure BFD protocol.
