rfc-ed note for draft-ietf-ospf-abr-alt

[Alex Zinin <zinin@psg.com>]

Please add the following rfc-ed note to draft-ietf-ospf-abr-alt:


Section 1.1 "Introduction", first paragraph

OLD:
   An OSPF routing domain can be split into several subdomains, called
   areas, which limit the scope of LSA flooding. According to [Ref1] a
   router having attachments to multiple areas is called an "area border
   router" (ABR).  The primary function of an ABR is to provide its
   attached areas with Type-3 and Type-4 LSAs (which are used for
   describing routes and ASBRs in other areas) as well as to perform
   actual inter-area routing.
