Hi Pushpasis,

Thanks for the review and comments.

Pls check if the below text looks good.

"
draft-ietf-spring-mpls-anycast-segments proposes a mechanism to allow the use of anycast SIDs in a network
where all devices do not share a common SRGB.  draft-ietf-spring-mpls-anycast-segments utilizes the concept of
a virtual LFIB, which is an application of  the concept of Context-Specific Label Spaces [RFC5331].  The current draft
uses the mechanism of context tables, a different application of Context-Specific Label Spaces, to facilitate node
protection.  The current draft does not make provisions to support the virtual LFIB mechanism together with
node protection context tables.  The use of anycast-SIDs together with anycast-aware TI-LFA provides effective
protection against node failure.  Therefore, when SRTE paths are constructed using anycast-SIDs, the anycast-SIDs
may not require node protection via context tables. "
