Chapter 19 Cisco ASR 1000 VxLAN Support
Configuring the Cisco ASR 1000 Routers as a VxLAN Layer 2 Gateway with Multicast
Mapping the VLAN to the Bridge Domain
You must map the VLAN created in the previous procedure to the bridge domain.
SUMMARY STEPS
1. bridge-domain bridge-id
2. member interface service-instance id
3. member vni vni-id
DETAILED STEPS
The following example displays the NVE VNIs configured on the router:
Router# show nve vni
Interface VNI mcast VNI state
nve1 1010 239.0.0.0 UP
nve2 2010 239.0.0.0 UP
Step 3
encapsulation dot1q vlan-ID
Example:
Router(config-if-srv)# encapsulation dot1q 100
Defines the VLAN encapsulation format as IEEE 802.1Q
and specifies the VLAN identifier.
Step 4
rewrite ingress tag pop 1 symmetric
Example:
Router(config-if-srv)# rewrite ingress tag pop
1 symmetric
Removes the VLAN tag in the Layer 2 traffic before
switching to the outgoing VxLAN interface.
Note This command is required to remove the VLAN tag
before sending the VLAN traffic to VxLAN and
adding the VLAN tag in the reverse direction.
Command or Action Purpose
Command or Action Purpose
Step 1
bridge-domain bridge-id
Example:
Router(config)# bridge-domain 10
Creates a bridge domain and enters bridge domain
configuration mode.
The valid range for bridge-id is 1-4096.
Step 2
member interface service-instance id
Example:
Router(config-bdomain)# member
gigabitEthernet 1 service-instance 1
Binds the bridge domain to the service instance.
Step 3
member vni vni-id
Example:
Router(config-bdomain)# member vni 1010
Maps the VNI to the bridge domain.
