enable loopback-mode vlan
Description
Allows a VLAN to be placed in the UP state without an external active port. This allows (disallows) the VLANs routing interface to become active.
Syntax Description
| vlan_name | Specifies a VLAN name. |
| vlan_list | Specifies a VLAN list of IDs. |
Default
N/A.
Usage Guidelines
Use this command to specify a stable interface as a source interface for routing protocols. This decreases the possibility of route flapping, which can disrupt connectivity.
