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
