Strict Downstream Alternates It is possible to provide link and node protection even in inapplicable scenarios – by requiring that the alternate is strictly closer to the destination than S, the link or the node being protecting. Substantially limits coverage – more restrictive than downstream paths. Cannot provide SRLG protection b/c SRLG protection is path based not distance based, and the path taken is unknown. May be useful for problems scenarios? Opinions? |
