Extend Policy - What is it?

[hgn]

Probably a example or two should be given: highest-bandwidth, highest-bandwidth-no-costs (one with filter)

Lines 152 to 157 in b5f4e5b

	Policy
	A Policy describes an order relation over a set of paths using the
	link attributes of these paths. Note that to guarantee loop-free
	properties this ordering function MUST be commutative and
	associative.

I thought of putting this in an Appendix, a ref to the appendix section would be good, though

I think we should define at least one required metric/policy for the standard. This is required to be interested op if a second router vendor will implement dmpr and will communicate with us.

Remember, metric name must not start with underscore for standardized protocol, vendor specific and experimental extension metrics must start with underscore.

So to rephrase my initial wordings: we must define at least one path metric/policy in the ID and give them a unique name.

Right?
