Hi, I'm trying to establish a peering session with another member of an IX (France-IX).
On my side I do have 2 OpenBSD (OpenBGPd) boxes. Config: group "peering" { holdtime 30 holdtime min 3 announce self set med 100 enforce neighbor-as yes max-prefix 1000 set community NO_EXPORT neighbor 193.105.232.181 { descr pv4_gw-003_to_ISC remote-as 30126 max-prefix 5 local-address 193.105.232.145 announce IPv4 unicast announce IPv6 none } neighbor 2001:7f8:54::181 { descr pv6_gw-003_to_ISC remote-as 30126 max-prefix 5 local-address 2001:7f8:54::145 announce IPv4 none announce IPv6 unicast } } In my logs I do observe this: Oct 9 09:44:40 bgpgw-003 bgpd[17498]: neighbor 193.105.232.181 (pv4_gw-003_to_ISC): state change Idle -> Connect, reason: Start Oct 9 09:44:40 bgpgw-003 bgpd[17498]: neighbor 193.105.232.181 (pv4_gw-003_to_ISC): state change Connect -> OpenSent, reason: Connection opened Oct 9 09:44:40 bgpgw-003 bgpd[17498]: neighbor 193.105.232.181 (pv4_gw-003_to_ISC): received notification: error in OPEN message, unknown subcode 8 Oct 9 09:44:40 bgpgw-003 bgpd[17498]: neighbor 193.105.232.181 (pv4_gw-003_to_ISC): state change OpenSent -> Idle, reason: NOTIFICATION received Oct 9 09:44:43 bgpgw-003 bgpd[17498]: neighbor 2001:7f8:54::181 (pv6_gw-003_to_ISC): state change Idle -> Connect, reason: Start Oct 9 09:44:43 bgpgw-003 bgpd[17498]: neighbor 2001:7f8:54::181 (pv6_gw-003_to_ISC): state change Connect -> OpenSent, reason: Connection opened Oct 9 09:44:43 bgpgw-003 bgpd[17498]: neighbor 2001:7f8:54::181 (pv6_gw-003_to_ISC): received notification: error in OPEN message, unknown subcode 8 Oct 9 09:44:43 bgpgw-003 bgpd[17498]: neighbor 2001:7f8:54::181 (pv6_gw-003_to_ISC): state change OpenSent -> Idle, reason: NOTIFICATION received Oct 9 09:44:44 bgpgw-003 bgpd[17498]: neighbor 2001:7f8:54::181 (pv6_gw-003_to_ISC): state change Idle -> Active, reason: Start Oct 9 09:44:44 bgpgw-003 bgpd[17498]: neighbor 2001:7f8:54::181 (pv6_gw-003_to_ISC): state change Active -> OpenSent, reason: Connection opened Oct 9 09:44:44 bgpgw-003 bgpd[17498]: neighbor 2001:7f8:54::181 (pv6_gw-003_to_ISC): state change OpenSent -> OpenConfirm, reason: OPEN message received Oct 9 09:44:44 bgpgw-003 bgpd[17498]: neighbor 2001:7f8:54::181 (pv6_gw-003_to_ISC): received notification: error in OPEN message, unknown subcode 8 Oct 9 09:44:44 bgpgw-003 bgpd[17498]: neighbor 2001:7f8:54::181 (pv6_gw-003_to_ISC): state change OpenConfirm -> Idle, reason: NOTIFICATION received On the peer logs we have (peer is a Cisco 7301 running IOS 15.01 shoult it matter): Oct 9 2012 18:24:25.731 UTC: BGP: 193.105.232.145 active went from Idle to Active Oct 9 2012 18:24:25.731 UTC: BGP: 193.105.232.145 open active, local address 193.105.232.181 Oct 9 2012 18:24:25.735 UTC: BGP: ses global 193.105.232.145 (0x6D6FC31C:0) act Remote close.
