Creating IS-IS topology independent LFA for prefix-SIDs learned from LDP mapping server

You can configure a point of local repair to create a topology independent loop-free alternate backup path for prefix-SIDs derived from LDP mapping server advertisements in an IS-IS network. In a network configured with segment routing, IS-IS uses the LDP mapping server advertisements to derive prefix-SIDs. LDP Mapping server advertisements for IPv6 are currently not supported. To attach flags to LDP mapping server advertisements, include the attached statement at the [edit routing-options source-packet-routing mapping-server-entry mapping-server-name] hierarchy level.
