Comment inline, begins with Zhenqiang. Zhenqiang Li 发件人: Les Ginsberg (ginsberg) 发送时间: 2010-04-22 14:41:46 收件人: Les Ginsberg (ginsberg); Tony Li; lizhenqiang@chinamobile.com; Jie Dong; bruno.decraene@orange-ftgroup.co; isis-wg@ietf.org; weifang@chinamobile.com 抄送: 主题: RE: [Isis-wg] draft-wei-isis-tlv-03 (Purge Originator Id) A couple of other comments that come to mind: We need to define what an implementation SHOULD do when it receives a purged LSP with the additional TLVs i.e. store it (including the body) and flood it unchanged. Zhenqiang: This is the normal processing, isn't it? If the same purged LSP is received from two different originators, the choice of which "copy" to flood is a local matter.
