Abstract
Methods and systems may be provided for detecting the moves of a multicast source. Sites that were previously designated as an active source may be immediately expired instead of waiting for route expiry. All multicast receiver sites may deterministically learn the new multicast source without additional LSP churn in ISIS for resolving the multicast source move conflict between the old and new source sites.
