Be cautious of content] Hi Ron, the readers would benefit if the draft would state that in order for the technology to work properly, there must be a contiguous set of connected routers that support it between the S/D, since lookup (route installed in context of the algo it is associated with) is done per hop.

An interface can be associated with, at most, one Flexible Algorithm. Likewise, an IP address can be associated with, at most, one Flexible Algorithm. I tried to express this in the text below, but probably didn't do a very good job. If you can think of a better way to say it, I would appreciate suggestions. Ron Text from draft ============ Network operators configure multiple loopback interfaces on an egress node. They can associate each loopback interface with: o Zero or more IP addresses. o Zero or one Flexible Algorithms. If an IP address and a Flexible Algorithm are associated with the same interface, they are also associated with one another. An IP address MAY be associated with, at most, one interface.

Be cautious of content] A quick question: If an IP address and a Flexible Algorithm are associated with the same interface, they are also associated with one another. An IP address MAY be associated with, at most, one interface. If multiple IP addresses and multiple flexible algorithms are associated with a loopback interface, is each IP address associated with all flexible algorithms? What matters is the association b/w an IP address and a flexalgo, so the relationship should be defined in a direct way rather than each being associated with an interface, right?
