Olá, estou com dificuldade em uma sessão ebgp ipv6 multihop utilizando 
Linux/Quagga.

Na verdade o problema é na recursividade das rotas, a sessão bgp subiu, 
recebi as rotas, mas elas ficam
inacessíveis via um link-local.

Vejam a configuração e o resultado abaixo...


eth2: 2804:15c:ca50:c::b/64
ipv6 route 2804:15c:ca5a::2021/128 2804:15c:ca50:c::a
neighbor: 2804:15c:ca5a::2021


router# show  ipv6  bgp
BGP table version is 0, local router ID is 187.85.150.81

internal,

Alguma sugestão?
