> Seems like ³marginal link² is associated with the IGP behavior No. A marginal link is simply one that has a measurable amount of packet loss.
On a properly functioning wired network, you don't have any marginal links: a link is either up or down, and a link that is up has negligible amount of packet loss (the link, not the switches). A marginal link is one that's neither up or down -- it's somewhere in between. This is made somewhat more complicated by layer 2 ARQ (for example, in 802.11b a link that is marginal at the physical layer will usually appear as merely slow for unicast traffic, but clearly marginal for multicast; weirder things are possible in 802.11a/g/n). > Is this close to what a ³marginal link² is? No. Being marginal is a property of a link, it has nothing to do with the IGP. -- Juliusz _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
