Hello.

S5710-EI
Software Version V200R005C00SPC500

I need to connect my S5710-EI to Route Reflector (Cisco) via MP-BGP. Connection state up in  "Estabished" but immediatly turn down to state "Idle".

Logs massege on S5710-EI tell me:

Oct 18 2018 22:19:51+05:00 Chernushka-US-R2 %BGP/3/STATE_CHG_UPDOWN(l)[60]:The status of the peer 172ublic, StateChangeReason=VPNv4 NLRI Parsed Error)



Complete code error - Update Messege Error (code 3), Optional attribute error (subcode 9).

But I do not understand what attribute is wrong.

Could you help me?

P.S. Wireshark dump, configurations and log masseges in add.

hi Evgen , i checked your provide logs and configuration , but seem the debugging information not completed . i cannot found any related error code for this neighbor 172.22.182.191 Down BGP Notification received .if we don't know the really error code for this issue , it's hard to locate the root cause .

Error Subcode 9 possible reason is error optional attribute , please check both device optional attribute whether configured the same .

if both device optional attribute configured the same ,i suggest you contact to local office or TAC support center . create SR ticket ask for support . and get the latest bgp debugging information and shared to us .
