Hi Tony, et al,
minor nit:
---
As an example, consider the Extended IS Reachability TLV (type 22).
A neighbor in this TLV is specified by:
* 7 octets of system ID and pseudonode number
* 3 octets of default metric
This acts as the key for this entry. The key is followed by up to
244 octets of sub-TLV information.
---
I believe that in most implementations the key in the LSDB is the 7 octets of
system ID and pseudonode number
and does not include the metric (it's really an attribute to the key), whereas
the current wording might
wrongly imply that the key is {sysid, PSN and metric}.
thanks,
/hannes

| Hi all,
|
|
|
| This is an update to reflect some of the discussions to date. A diff is
| attached. Most of this is a change to terminology to stop using the word
| ‘instance’ and shift to using ‘multi-part TLV’.
|
|
|
| We have been having a discussion about adding more discussion of keys in
| this document. We have not done that yet. This is not an indication of
| refusal, just making one baby step forward. More to come… Text
| contributions are more than welcome.

| Abstract:
| New technologies are adding new information into IS-IS while
| deployment scales are simultaneously increasing, causing the contents
| of many critical TLVs to exceed the currently supported limit of 255
| octets. Extensions such as [RFC7356] require significant IS-IS
| changes that could help address the problem, but a less drastic
| solution would be beneficial. This document codifies the common
| mechanism of extending the TLV content space through multiple TLVs.
