Hi Wang, Most implementations would just drop the corrupted LSPs - the problem you describe wouldn't occur if you did this. Cheers, Manav _____ From: Theodore.Wang [mailto:theodore.wang@gmail.com] Sent: Sunday, October 14, 2007 4.44 PM To: isis-wg@ietf.org Subject: [Isis-wg] Question about Purge LSP in RFC 1142 Hi, all I have a question about Purge LSP in RFC 1142. In RFC 1142, I find the following lines: e)An Intermediate system receiving a Link State PDU with an incorrect LSP Checksum or with an invalid PDU syntax shall 1)log a circuit notification, corruptedLSPReceived, 2)overwrite the Checksum and Remaining Lifetime with 0, and 3)treat the Link State PDU as though its Remaining Lifetime had expired These lines define the way how to cope with the LSP with incorrect checksum, that is to flood the LSP's header with zero remaining lifetime. But in fact, in a huge network, it is hard to locate the router that generate the Purge LSP, and which is the situation I'm facing. A Corrupted LSP Storm is happening in the network and it lacks a efficient way to troubleshooting because we can only use "ignore checksum error" on every router to find the one that flooded the Purge LSP. Therefore, is it possible to attach a new TLV in Purge LSP that defines the originator? Thanks in advance!
