[GTER] Problemas na sessão do Cymru.

[Kalil de A. Carvalho]

Bom dia a todos.

A algum tempo uma das nossas sessões com o Cymru ficou "*Idle*" sem motivo
aparante, tendo em vista que não foi modificado nada e a outar sessão esta
normal.

O que é mais estranho é que guando vamos verificar a sessão a saída é esta:

O que me chamou a atenção é que mostra duas sessões, uma com "remote AS 0,
local AS 0" que não sei de onde ele tirou essa informação.

Tentando corrigir refiz a configuração e tentei subir a sessão, porem agora
estou recebendo este retorno:

%NOTIFICATION: received from neighbor 193.231.140.82 2/8 (OPEN Message
ErrorUnrecognized Error Subcode) 3 bytes 00 00 00

A unica coisa que desapareceu, quando dou o comando "show ip bgp neighbor
193.231.140.82" é o "remote AS" que agora não aparece mais o 0.

Alguém já passou por isso? Tem alguma ideia de como resolver?

Atenciosamente,
