Hi all, The significant change between -00 and -01 is the addition of the "length" indicator as suggested by Bruno Decraene. I manually created a PCAP file to show what the shutdown communication looks like on the wire. This file can be used to test wireshark, tcpdump and other packet analysers. http://instituut.net/~job/shutdown.pcap This is the frame of interest: Vurt:~ job$ tcpdump -XX -r shutdown.pcap -c 4,5 -v reading from file shutdown.pcap, link-type EN10MB (Ethernet) 20:19:25.904210 IP (tos 0xc0, ttl 64, id 53942, offset 0, flags [DF], proto TCP (6), length 198) shutdown.meerval.net.45016 > kiera.meerval.net.bgp: Flags [P.], cksum 0x9754 (correct), seq 791846767:791846913, ack 3734170538, win 2048, options [nop,nop,TS val 1416108449 ecr 4177813403], length 146: BGP Notification Message (3), length: 146, Cease (6), subcode Administratively Shutdown (2) 0x0000: 5254 0097 e0df 5254 0021 7f49 0800 45c0 RT....RT.!.I..E. 0x0010: 00c6 d2b6 4000 4006 1c8b a5fe ff18 a5fe ....@.@......... 0x0020: ff1a afd8 00b3 2f32 9f6f de92 ebaa 8018 ....../2.o...... 0x0030: 0800 9754 0000 0101 080a 5468 19a1 f904 ...T......Th.... 0x0040: 5f9b ffff ffff ffff ffff ffff ffff ffff _............... 0x0050: ffff 0092 0306 027f 4e54 5420 7769 6c6c ........NTT.will 0x0060: 2070 6572 666f 726d 206d 6169 6e74 656e .perform.mainten 0x0070: 616e 6365 206f 6e20 7468 6973 2072 6f75 ance.on.this.rou 0x0080: 7465 722e 2054 6869 7320 6973 2074 7261 ter..This.is.tra 0x0090: 636b 6564 2069 6e20 5449 434b 4554 2d31 cked.in.TICKET-1 0x00a0: 2d32 3438 3234 3239 342e 2043 6f6e 7461 -24824294..Conta 0x00b0: 6374 206e 6f63 406e 7474 2e6e 6574 2066 ct.noc@ntt.net.f 0x00c0: 6f72 206d 6f72 6520 696e 666f 726d 6174 or.more.informat 0x00d0: 696f 6e2e ion.
