#5: only one default route?  (there should be multiple, as for MIF WG)


Comment (by alexandru.petrescu@…):

 I will write this down here so I have a trace.

 I discussed 1aug2012 with a co-author and there seems to be strong
 opposition to multiple default routes for the following reasons.

 If a Host has several interfaces, then on each of these interfaces there
 would be different responding DHCP Server that would allocate data
 specific to that interface in particular.  It would be not reasonable for
 a DHCP Server answering to one interface of a Host to offer it
 configuration information for the other interface.

 An operator of both WiFi and 3G would deploy a different DHCP Server on
 each of the access routers of 3G and of WiFi (and would not use same DHCP
 Server to configure the cellular interface and the WiFi interface of the
 same Host).

 If you have two default routes in the same host then how to decide which
 is _the_ default route?  This is bad because it is difficult to decide so.
 Source-based routing is not good (I forgot why).

 Alex
