Tue Jun 17 04:27:40 EDT 2008

Hi,

I've flapping between SE and T640 : Hereafter some logs : 

Jun 17 07:28:57  ncidf303 rpd[16196]: RPD_ISIS_ADJDOWN: IS-IS lost L2 adjacency to SE800 on ae8.1456, reason: Address Mismatch
Jun 17 07:29:04  ncidf303 rpd[16196]: RPD_ISIS_LSPCKSUM: IS-IS L2 LSP checksum error, interface ae8.1456, LSP id nclyo302.00-01, sequence 0x418, checksum 0xd308, lifetime 60148
Jun 17 07:29:07  ncidf303 rpd[16196]: RPD_ISIS_LSPCKSUM: IS-IS L2 LSP checksum error, interface ae8.1456, LSP id ncstr102.00-00, sequence 0x8bab, checksum 0x81c7, lifetime 35134

Each time we've the "Address Mismatch" we've also the log "LSP checksum error"

Regards,
David
