BGP suddenly failed without a reason
« on: July 16, 2011, 05:57:38 am »
Please help me .

My router MX480 connect to 3 differences ISPs , but sometimes , the BGP connections suddenly reset ( Flap increase )
I show log messages and It show me that BGP_RECV failed .

mx480 rpd[1308]: bgp_recv: read from peer xxxxxxxxx (External AS xxxxx) failed: Connection reset by peer
mx480 rpd[1308]: bgp_recv: read from peer xxxxxxxxxx (External AS xxxxx) failed: Connection reset by peer
mx480 rpd[1308]: bgp_recv: read from peer xxxxxxxxx(External AS xxxxxxx) failed: Connection reset by peer

I suspect this problem relate to OS or Hardware .

Please help me
Thank you .

Have you enabled BGP MD5 authentication?  Unlikely but maybe you're being attacked.

I don't enable BGP MD5 Authentication . And I think attack is impossible , because this problem happned anytime ( day or midnight) .
