Como vimos em nossa seria de artigos de criação de vnet, peering, bgp e VPN IPSec com BGP, vamos criar mais uma vnet em nossa infraestrutura já existente. Veja nossos artigos nas sequencia:

Criando Vnet com Tags via CLI (Bash) Azure
Criando Virtual Network Gateway (VPN com BGP) Azure via CLI (Bash)
Criando Virtual Network com Peering via CLI (Bash) Azure
Criando Peering Virtual Network (Azure) via CLI (Bash) com Gateway de propagação.
Criando Local Network Gateway com BGP – VPN IPSec Fortigate.

Veja o resultado

Em nosso fortigate

Com isso concluimos nossa seria de Vnet com peering e propagação BGP, a cada vnet nova criada com peering (utilizando as configuração aqui exibidas) não é necessário fazer mais nada em nosso fortigate ou Gateway de VPN, um lembrete muito importante as redes não podem se sobscrever (Over lapping).
