Section 12.4.1 says:
Router-LSAs
If the state of the interface is Loopback, add a Type 3
link (stub network) as long as this is not an interface
to an unnumbered point-to-point network. The Link ID
should be set to the IP interface address, the Link Data
set to the mask 0xffffffff (indicating a host route),
and the cost set to 0.
===================================
12.4.1.4. Describing Point-to-MultiPoint interfaces
For operational Point-to-MultiPoint interfaces, one or
more link descriptions are added to the router-LSA as
follows:
o A single Type 3 link (stub network) is added with
Link ID set to the router's own IP interface
address, Link Data set to the mask 0xffffffff
(indicating a host route), and cost set to 0.
=============================================================================
C.3 Router interface parameters
Interface output cost
The cost of sending a packet on the interface, expressed in
the link state metric. This is advertised as the link cost
for this interface in the router's router-LSA. The interface
output cost must always be greater than 0.
It should say:
"cost set to 0" to at least "greater than 0"
Notes:
The section 12.4.1 and 12.4.1.4 are inconsistent with the appendix c.3.
These both section we find the cost to stub networks have to be set to 0, but in appendix c.3 we see that the interfaces must have greater than 0.
--VERIFIER NOTES--
A discussion on the WG list (lsr) resulted a consensus of no change needed.
