[j-nsp] Insane BGP Log messages - what do they mean?

[STEWART KIRK]

Hi

 

Quick question - We have recently experienced a problem where due to a
faulty equipment downstream from a Juniper router we were experiencing
loss of BGP keepalive messages and therefore experiencing some
instability due to BGP going up and down.

This has been resolved but on examination of the logs on the Juniper
router (M40e) we have noticed that there are some log messages relating
to seeing extra data which was 'probably insane'  - does anyone know
what this means?

 

example

Jan  1 14:40:17.758 2008  NN-IP_RE0 rpd[3281]: %DAEMON-4:
bgp_traffic_timeout: NOTIFICATION sent to xxx.xxx.xxx.xxx (Internal AS
YYYY): code 4 (Hold Timer Expired Error), Reason: holdtime expired for
xxx.xxx.xxx.xxx (Internal AS YYYY), socket buffer sndcc: 57 rcvcc: 0 TCP
state: 4, snd_una: 2706114888 snd_nxt: 2706114926 snd_wnd: 15928
rcv_nxt: 3229612859 rcv_adv: 3229665384, keepalive timer 0

Jan  1 14:41:33.364 2008  NN-IP_RE0 rpd[3281]: %DAEMON-4: bgp_pp_recv:
peer xxx.xxx.xxx.xxx (Internal AS YYYY) sent unexpected extra data,
probably insane

 

Your assistance is appreciated
