Hi all,

why do we use of loopback interface as WAN link with color assigned in Viptela SDWAN

like binding physical interface going to MPLS link under loopback interface and assignning private6 color to loopback interface and giving Private5 to Mpls physical link

Hi,

There are different use cases where loopback interface need to be configured.
Take a look at the Design Guide: https://www.cisco.com/c/en/us/td/docs/solutions/CVD/SDWAN/cisco-sdwan-design-guide.html#LoopbackInterfaceTunnels
