Balance em si não eh bom... faça da maneira certa, crie 2 redes e cada uma sai por um link, quando o link da rede A cai você joga tudo para o link da rede B.

o pessoal pode dizer o problema do PCC? tenho 3 links com pcc, gostaria de saber quais os problemas para eu analisar se vale a pena outra forma de roteamento
