O Network Connectivity Center fornece conectividade de malha completa entre cada spoke com
o recurso de transferência de dados ativado. Se todos os spokes tiverem o recurso ativado,
o Network Connectivity Center propagará todas as rotas que um spoke aprender para os demais
spokes.
Topologia da central de conectividade de rede (clique para ampliar)
Na topologia anterior, os Spokes A, B e C estão associados ao mesmo hub
e usam o Cloud Router para divulgar prefixos no hub.
Para ativar o tráfego de local para local em várias regiões por hubs e spokes, é necessário
ativar o roteamento global
na rede VPC associada aos hub e spokes.
Se todos os spokes estiverem localizados na mesma região, o roteamento global não
será necessário, porque o tráfego de local para local funciona sem ativar o roteamento global.
A tabela a seguir mostra como o hub propaga divulgações de prefixo para
outros spokes.
