RFC Editor's Note:
Section 3.7 "Sub-TLV 18: Traffic Engineering Default metric"
Second para:
OLD:
To preclude overflow within a SPF implementation, all metrics greater
than or equal to MAX_PATH_METRIC SHALL be considered to have a metric
of MAX_PATH_METRIC. It is easiest to select MAX_PATH_METRIC such
that MAX_PATH_METRIC plus a single link metric does not overflow the
number of bits for internal metric calculation. We assume that this
is 32 bits. Thus, MAX_PATH_METRIC is 4,261,412,864 (0xFE000000, 2^32
- 2^25).

Section 6.2.1 "Sub-TLVs for TLV 22"
OLD:
This registry contains codepoints for Sub-TLVs of TLV 22. The range
of values is 0-255. Allocations within the registry require
documentation of the use of the allocated value and approval by the
Designated Expert assigned by the IESG (see [5]).
