=09It's hard to generally categorize special needs because they're=
special. I
can give you an example of a special need, but it hardly typifies=
all the
special needs.
=09One example of a special need would be a case where you get a=
100Mbps
connection from a transit provider and you don't use BGP. They=
normally
assign two IPs, one to each end of the link. You want to connect=
the link to
a switch and number two routers inside the link using HSRP for=
which router
they send your traffic to.
=09Another case might be where you get 2 100Mbps links and you want=
both
failover and load sharing. You might want them to allow a setup=
where each of
the two links goes to two routers (through switches) such that=
either router
can use either link under normal conditions. This way you're=
protected
against failure of either router, either link, and under normal=
conditions
can get the full use of both. This may require configuration=
changes on their
end (such as the subnet mask of the block the link is numbered=
with.)
=09What I think you don't realize is how precisely Cogent specifies=
everything.
Anything other than exactly their default configuration is a=
special need
they won't do.
