Acee/Ben, Updated the text as below. <t> Multiple node administrative tag TLVs MAY appear in an RI LSA or multiple node administrative tag TLVs MAY be contained in different instances of the RI LSA. The node administrative tags associated with a node that originates tags for the purpose of any computation or processing at a receiving node SHOULD be a superset of node administrative tags from all the TLVs in all the received RI LSA instances in the Link-State Database (LSDB) advertised by the corresponding OSPF router.When an RI LSA is received that changes the set of tags applicable to any originating node, a receiving node MUST repeat any computation or processing that is based on those administrative tags. </t> Rgds Shraddha -----Original Message----- From: Benjamin Kaduk [mailto:kaduk@MIT.EDU] Sent: Thursday, October 15, 2015 6:28 AM To: Acee Lindem (acee) <acee@cisco.com> Cc: Shraddha Hegde <shraddha@juniper.net>; iesg@ietf.org; secdir@ietf.org; draft-ietf-ospf-node-admin-tag.all@ietf.org Subject: Re: secdir review of draft-ietf-ospf-node-admin-tag-05 On Wed, 14 Oct 2015, Acee Lindem (acee) wrote: > Hi Ben, > > On 10/13/15, 7:02 PM, "Acee Lindem (acee)" <acee@cisco.com> wrote: > > > > > > >On 10/13/15, 6:57 PM, "Benjamin Kaduk" <kaduk@MIT.EDU> wrote: > > > >>Thanks for clarifying.
