Boa tarde lista,

a mais de 24 horas tenho notado sérios problemas de rota via IPv6 entre
Copel Telecom e Claro.

Ao meu entender a Copel (AS14868) está usando a Claro/Embratel (AS4230)
como carrier para IPv6 nas rotas internacionais, mas algumas delas
apresentam perda de 100% dos pacotes, impossibilitando acesso a recursos,
ping e tracert.

Meu problema em específico está com a conexão a AS16276 (OVH SAS) onde
nenhum recurso é alcansável via IPv6, mas notei problemas de rotas para
algumas outras AS com menor impacto para mim.


Abaixo compartilho o resultado de um simples mtr (primeiro ao Google OK e o
segundo a um endereço IPv6 na AS16276)
