Chapter 19 Cisco ASR 1000 VxLAN Support
Configuring the Cisco ASR 1000 Routers as a VxLAN Layer 2 Gateway with Unicast
The following example displays the NVE VNIs assigned to NVE interface 1:
Router(config)# show nve vni interface nve1
Interface VNI mcast VNI state
nve1 1010 239.0.0.0 UP
nve1 1110 239.0.0.0 UP
The following example shows the status of NVE interface 1:
Router(config)# show nve interface nve1
Interface: nve1, State: Admin Up, Oper Up Encapsulation: Vxlan
source-interface: Loopback0 (primary:11.11.11.11 vrf:0)
The following example shows a detailed display for NVE interface 1:
Router(config)# show nve interface nve1 detail
Interface: nve1, State: Admin Up, Oper Up Encapsulation: Vxlan
source-interface: Loopback0 (primary:11.11.11.11 vrf:0)
Pkts In Bytes In Pkts Out Bytes Out
0 0 0 0
The following example shows the NVE peers configured on the router:
Router(config)# show nve peers
Interface Peer-IP VNI Up Time
nve1 1.1.1.2 1010 10h
nve2 1.1.1.3 2030 20h
The following example shows the bridge domain configuration with the entry in bold displaying the
VM’s MAC address that was learned on the VxLAN VNI:
Router# show bridge-domain 1000
Bridge-domain 1000 (3 ports in all)
State: UP Mac learning: Enabled

Gateway with Unicast
The following example shows VxLAN with unicast ingress-replication which is a point-to-point
(unicast) configuration.
