[c-nsp] BGP cause dropped packet

[ไอดิน กลิ่นฝัน]

Hello,

I have some problem about BGP ipv6 and need your kindly advice.

I have 2 router  CISCO7606-S 12.2(33)SRE1 as core router redundancy,
normally using eBGP with any other routers. Right now, I need to enable BGP
IPv6 on both routers. One of them has experienced dropped packet whenever
enable BGP IPv6, if disable, then no any dropped packet, but another has
not. Do you have experience this before, can you please advice how to
investigate this problem?

After disable BGP IPv6, no any lost packet.
