bfd vtep evpn
The bfd vtep evpn command to configure the BGP PIC Edge for EVPN VXLAN routes for remote VTEPs. This command is configured under the VXLAN Tunnel Interface (VTI).

show vrf leak flapping
The show vrf leak flapping command displays the flapping prefixes of the routes leaked from one VRF to another VRF. Routes that are detected as “flapping” are blocked considering the future leaking policy execution.
Command Mode
EXEC
Command Syntax
show vrf leak flapping
- destination displays flapping prefixes destined to a VRF.
- prefix displays flapping routes for a prefix.
- source displays flapping prefixes sourced from a VRF.
- vrf displays flapping prefixes associated with a VRF.

To enable the user to quickly view which control planes and sources are importing reachability information into which VLANs, use the following show command:
Command Mode
EXEC
show VXLAN control-plane [ export vlan [ $ | vlan_id]|import vlan [$ | vlan_id]][vlan [$ | vlan_id]
- export Restricts output to VLANs exporting to a
control plane.
- vlan Specifies specific VLANs to display
control plane information.
- $ List end.
- vlan_id VLAN ID. Range 1-4094.
- vlan Specifies specific VLANs to display
control plane information.

vlan (VLAN-AWARE-Bundle configuration mode)
The vlan add/ remove command configures the VLAN range string in a VLAN-AWARE-BUNDLE. When the add and remove options are not used, the currently configured range is replaced by the new one . The add and remove options update the currently configured range-aware bundles by adding or removing the provided VLAN range from the currently configured range respectively.
Command Mode
VLAN-AWARE-BUNDLE Configuration
Command Syntax
vlan [add | remove] range
Parameters
range is the range specified.
Example
These commands take an existing vlan-aware-bundle configuration, corporate_100, and modify it with the add and remove options.
(Existing configuration for corporate_100)
vlan-aware-bundle corporate_100
rd 1.1.1.1:100
route-target both 100:100
vlan 1-10
switch(config-vlan-aware-bundle)#vlan add 1000
(Modified configuration for corporate_100)
vlan-aware-bundle corporate_100
rd 1.1.1.1:100
route-target both 100:100
vlan 1-10, 1000
switch(config-vlan-aware-bundle)#vlan remove 5
(Updated configuration for corporate_100)
vlan-aware-bundle corporate_100
rd 1.1.1.1:100
route-target both 100:100
vlan 1-4, 6-10, 1000
vni-aware-bundle
The vni-aware-bundle command configures a BGP MAC-VRF containing Layer 2 routes from a group of VXLAN Network Identifiers (VNI).
Command Mode
Router BGP Configuration
Command Syntax
vni-aware-bundle vni_bundle_name
Parameter
vni_bundle_name VNI bundle name.
Example
This command configures MAC-VRF BGP to support VNI bundle1.
