>From Kathy's lips:
"One of the R&S lab rules state that no routes to Null are
allowed unless otherwise stated in the lab. In the context the rule was
given it seemed that one is not allowed to create static routes to Null
but that routes to Null generated by a routing protocol (such as
summarization in OSPF) are allowed in the routing table. In an attempt
to clarify this I asked the proctor this very question and I was told
that routes to Null generated by a routing protocol are fine. However,
in looking at various CCIE resources, newsgroups, etc. it seems many
people believe that absolutely no routes to Null are allowed, whatever
the source."
"Can you folks settle this question once and for all, (since it
would have made a great difference in how I approached some of my
solutions during my lab attempt if routes to Null generated by a routing
protocol are not allowed)?"
"When folks ask me this question in the lab, I turn them to page
four of the test, where the general guidelines are listed: and I quote
rule number one: 1 Static and default routes are not permitted unless
directly stated in a question. This includes floating static, static
routes
to Null0 and routes to Null0 generated by any routing protocol."
"An explicit allowance within a test question will override this
rule. However I think the general guidelines spells it out pretty well."
