I don’t think so, but I’m not a routing person. I wouldn't think that an internal loopback address would be widely used. In fact, I checked our Cisco native models for IOS-XE and there is no such definition. [Qin]: I am not sure we are talking about loopback type or loopback address See section 2.4 in draft-ietf-netmod-intf-ext-yang-10, 3 type loopbacks are defined: 1.Internal loopback 2.Line loopback 3.Loopback Connector 3 types loopback can be classified into local loopback and remote loopback. I am not sure they are common, but we have some support for this. This is the loopback address type - not the loopback interface type. Look at draft-nainar-mpls-lsp-ping-yang (the draft being discussed in the Email thread).
