What happened to ppvpn wg? My colleagues' e-mail and  mine are always
rejected?
especially during the days prior to the 57th IETF meeting.

Could you please help address this problem?

Thank you very much!

Hi,

In Section 4 Extranet VPN Processing of
draft-behringer-mpls-vpn-auth-02.txt,it states that "There are typically two
types of Extranets that can be defined using the [RFC2547] architecture;
Central Services Extranet and Distributed Extranet."

I can't figure out the scenarios of the two types of Extranets,especially
the topology,Could you please clarify them to me with the illustration of
topology of the two types of Extranets.

Sincerely Yours
