Ajuda com PCC MK

Olá... Bom Dia a todos...

Estou com o seguinte problema no meu balanceamento e gostaria da ajuda de voces.
Tenho uma Rb 450 fazendo o balanceamento PCC de 2 link
Link 1 ether1 2048 kbps ( Provedor local )
Link 2 ether2 600 kbps ( velox )

O que esta acontecendo é o seguinte, se eu estiver consumindo os 2048 k do meu link 1, ele nao balancea nada para o link 2, o link 2 fica parado.
Mas se qualquer um dos links cair o outro assumi normal.

aqui estao as minhas regras de mangle.
Grato a todos que contrinuirem comigo.

bom dia colega

me passe o seu cenario

ether1 (funcao e ip)
ether2 (funcao e ip)
ether3 (funcao e ip)
ether4 (funcao e ip)
ether5 (funcao e ip)

eth1 = recebe o link de 2mb ip 192.168.5.149 gatway 192.168.5.1
eth2 = recebe o link de 600k ip 192.168.1.150 gatway 192.168.1.1
eth3 = links balanceados.
eth4 e 5 em bridge com a eth3

as interfaces que tu recebe o link não devem estar em bridge
