A seis meses a traz,um cliente me disse que desejava centralizar seu serviço, mas queria uma rede roteada,lembrando que sua rede era wifi e em bridge,propus que foce uma rede mpls.
porque?
porque acelera a entrega de pacotes,reduz saltos,processamento,alem da facilidade de se chegar aos distribuidores com serviços (ip publico,hotspot,voip,pppoe e etc).
em fim apos 6 meses de sucesso resolvi compartilhar a ideia do projeto.
ressalvas:
isso não e um tutorial,pra você utilizar tuneis sugiro que conheça roteamento estático,não utilizo ospf em redes pequenas.
O projeto real foi feito com um pc de centralizador e stx,rb 2011,ominitik como distribuidores, assim
distribuidores, em meus testes utilizei rb450g sxt,rb750g.
resultado final:
menor latência,throughput da rede passou de 40MB para 95MB,processamento reduziu 48%.
considerações :
criar uma bridge loopback em todos roteadores.
nao utilizar WDS nos enlaces,utilizar somente o protocolo NV2

utilizando o diagrama acima vamos configurar os roteadores

Pronto basta agora usar as interfaces vpls-hotspot e vpls-pppoes para criar os devidos serviços,lembrando que tudo deve ser feito no R1 e no R2 basta criar uma bridge e adicionar a interface e a vpls serviço.
