Could not get mac address for nic: software loopback interface 1 udeploy agent

clagd (the daemon responsible for MLAG) adds the anycast address to the loopback interface as a second address.

MLAG peering takes place and a successful VXLAN interface consistency check between the switches occurs.

The configured anycast addresses are not configured yet.

When the switches boot up, ifupdown2 places all VXLAN interfaces in a PROTO_DOWN state.

clagd dynamically adds and removes this address as the loopback interface address as follows: The VXLAN termination address is an anycast IP address that you configure as a clagd parameter ( clagd-vxlan-anycast-ip) under the loopback interface. You must provision each individual switch within an MLAG pair with a virtual IP address in the form of an anycast IP address for VXLAN data-path termination. Example configurations are provided below. You must enable BPDU filter and BPDU guard in the VXLAN interfaces if STP is enabled in the bridge that is connected to the VXLAN. Example configurations for BGP are provided below. Refer to OSPF or BGP for more detailed configuration information. Refer to MLAG for more detailed configuration information. VXLAN active-active mode requires the following underlying technologies to work correctly. The anycast address for the MLAG pair to share and bind to when MLAG is up and running. The industry standard term for the ability to route in and out of a VXLAN. Allows a VXLAN bridge to have a switch VLAN interface associated with it, and traffic to exit a VXLAN into the layer 3 fabric. A Broadcom feature for routing in and out of tunnels. With VXLAN, anycast is used to share a VTEP IP address between a pair of MLAG switches. Anycast enables multiple devices to share the same IP address and effectively load balance traffic across them.
