> Current Ethernet (802.1) link layers use custom routing protocols
> that have a number of challenges. These routing protocols need to
> strictly avoid loops, even temporary loops during route propagation,
>
>
>  because of the lack of header loop detection support. Routing tends
> not to take full advantage of alternate paths, or even non-
> overlapping pairwise paths (in the case of spanning trees). The
> convergence of these routing protocols and stability under link
> changes and failures is also of concern. This document addresses
> these concerns and suggests that they are related to the need to be
> able to apply modern network layer routing protocols at the link
> layer. This document assumes that solutions would not address issues
> of scalability beyond that of existing bridged (802.1) links, but
> that a solution would be backward compatible with 802.1, including
> hubs, bridges, and their existing plug-and-play capabilities.
