Because, most if not all IPv6 implementations come with a mandatory ND implementation. That has the notion of "default router". That default router has a mandatory lifetime field. There can be several routers on a link acting as a "default router" and their lifetime. RFC4861 syas "The Router Lifetime applies only to the router's usefulness as a default router; it does not apply to information contained in other message fields or options. Options that need [...]" in sync with lifetimes communicated by ospf. > Why do we need a default route option at all? Because it is more important than the specific routes. It must work when everything else fails. Must be distinguishable when several present; must be reliably renewed even though no global address assigned with DHCP; must be in sync with what RA does. Must tell the number of hops between Client the gw address. Etc. If some of these aspects fail the Client without a default route may be unreachable by arbitrary nodes trying to ICMP diagnose it. On another hand, a specific route incompletely specified may not do that much harm to Client. > It doesn't look like the use case you've proposed justifies this > option. Hmmm... I am not sure whether you're saying that these aspects (interface name resolution, number of hops, sync with ND/rt protocols) are necessary for all other specific routes as well. Or you're saying simply that the currrrent draft-mif is ok as it is with its way of being extended. Alex >
