Hi
What does the following
sentence (section 3.4.3.7) in the RFC 2740 mean?
Router RTX
examines its list of interfaces to the area. If the
interface is in state Down, its prefixes are not included. If
the
interface has been reported in RTX's router-LSA as a Type 2
link
description (link to transit network), its prefixes are
not
included (they will be included in the intra-area-prefix-LSA
for
the link instead). If the interface type is
Point-to-MultiPoint,
or the interface is in state Loopback, or the interface
connects
to a point-to-point link which has not been assigned a
prefix,
then the site-local and global scope IPv6 addresses
associated
with the interface (if any) are copied into the
intra-area-
prefix-LSA, setting the LA-bit in the PrefixOptions field,
and
setting the PrefixLength to 128 and the Metric to
0.
Otherwise,
the list of site-local and global prefixes configured in RTX
for
the link are copied into the intra-area-prefix-LSA by
specifying
the PrefixLength, PrefixOptions, and Address Prefix fields.
The
Metric field for each of these prefixes is set to the
interface's
output cost.
Considering the
following example
RTA<serial
1>-------------------<serial1>RTB
Does it mean that RTA
will advertise the prefix configured on serial 1 with LA bit set, iff there is
no prefix configured on the serial1 of RTB?
Thanx and
regards
