Hi Dhananjaya and WG, We have a solution to solve the same problem ,the link is https://tools.ietf.org/html/draft-zhou-idr-inter-domain-lcu-02,This document describes the colored BGP-LU LSP, in which the routing prefix not only carries a label(or a sequence of labels), but also carries an unique color attribute which helps to select the underlying logic slice. [RFC7911] defines a BGP extension that allows the advertisement of multiple paths of the same address prefix. It can help with optimal routing and in a network by providing potential alternate or backup paths. In this document, it is not used for the link backup. It is only used to advertise multiple paths, whether intra-domain or inter-domain. Appreciate if you could review and give us comments. Best Regards, Ran
