The following errata report has been submitted for RFC4577,
"OSPF as the Provider/Customer Edge Protocol for BGP/MPLS IP Virtual Private Networks (VPNs)".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=4577&eid=2264

--------------------------------------
Type: Technical
Reported by: William McCall <william.mccall@gmail.com>

Section: 4.2.6

Original Text
-------------
[...] If BGP installs a route of one of these types in the VRF, and if that route is selected for redistribution into OSPF, it will be advertised by OSPF in either a type 3 or a type 5 LSA, depending on the domain identifier.


Corrected Text
--------------
[...]If BGP installs a route of one of these types in the VRF, and if that route is selected for redistribution into OSPF, it will be advertised by OSPF in either a type 3, type 5, or type 7 LSA, depending on the domain identifier and the type of area the PE/CE link belongs to.

Notes
-----
Suggested because reading 4.2.6 is contradictory with the following:

4.2.8.1.  External Routes

[...]If the route is advertised, and the PE/CE link belongs to a NSSA area, it is advertised in a type 7 LSA.[...]

Instructions:
-------------
This errata is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party (IESG)
can log in to change the status and edit the report, if necessary.
