ospfd: respect max-metric over configured cost for summary LSAs
ISSUE When max-metric router-lsa administrative is invoked on an ABR created with... area <area> range <addr/mask> the summary LSAs are sent out with 65535 (max-metric) added to the normal cost. When max-metric router-lsa administrative is invoked on an ABR created with... area <area> range <addr/mask> cost <cost> the summary LSAs are sent out with <cost> (the max-metric is ignored). This second behavior effectively incapacitates the max-metric function. PATCH This patch evaluates the state of the router and if it's isolated as a stub router (rfc3137) via `max-metric router-lsa`, we unconditionally uses the value of 0xff0000 when advertising summary LSAs.
