Re: [Isis-wg] Link-State Routing WG charter

Hi Les,

Thanks for the suggestions!  I've modified the paragraph about IS-IS to
read:

"IS-IS is an IGP specified and standardized by ISO through ISO 10589:2002
and additional RFC standards with extensions to support IP that has been
deployed in the Internet for decades.  For the IS-IS protocol, LSR-WG’s
work is focused on IP routing, currently based on the agreement in RFC 3563
with ISO/JTC1/SC6. The LSR-WG will interact with other standards bodies
that have responsible for standardizing IS-IS. LSR-WG will continue to
support Layer 2 routing (for example TRILL work) as needed."

and updated to "In addition to ongoing maintenance, the following topics
are expected to be among the work-items at the time of chartering." to
clarify that the list isn't constrictive.

I didn't go for IP/IPv6 since IP should cover both IPv4 & IPv6.

The updated version (with Stewart's comments addressed as well) can be
found as charter-ietf-lsf-00-04 at:

https://datatracker.ietf.org/doc/charter-ietf-lsr/

Regards,
Alia
