Hi, Section 2.11 says two slightly ambiguous things:
1. Generally, only valid SR policies are instantiated in the forwarding plane. This means that sometimes non-valid SR policies are instantiated in the forwarding plane. But I don't see anything in the text to say when or why that would be done. Can anyone provide an explanation? 2. Only the active candidate path MUST be used for forwarding traffic that is being steered onto that policy except for certain scenarios such as fast reroute where a backup candidate path may be used as described in Section 9.3. As written this implies that there is no prohibition to use other candidate paths. I suspect that this is not what was meant. Part of the problem is caused by the use of the passive voice. If we insert a responsible actor we may get closer to what the working group intended which is, I think, as follows: A headend node MUST use only the active candidate path for forwarding traffic that is being steered onto that policy, except for certain scenarios such as fast reroute where a backup candidate path MAY be used as described in Section 9.3. Is this correct? Many thanks, Adrian _______________________________________________ spring mailing list -- [email protected] To unsubscribe send an email to [email protected]
