Erro no Terminal e outras questões

Estava pronto para implantar meu Load Balance através de um script que fui editando a minha realidade.
A linha é esta abaixo:

Tenho as seguintes questões:

1) Quando a linha abaixo, ocorre o erro descrito na foto 1
add chain=prerouting src-address-list=odd in-interface= Clientes action=mark-connection \ new-connection-
mark=odd passthrough=yes

OBS: me falaram que onde tem odd, é para ser add
Mas mesmo assim, deu o seguinte erro:
[admin@MikroTik] > add chain=prerouting src-address-list=add in-interface=Clientes action=mark-connection \ new-connection-mark=add passthrough=yes

bad command name add (line 1 column 1)



2) O link padrão embratel é discado (modem brigge), enquanto o velox é roteado
Na linha onde atribuo router embratel, está certo eu colocar o IP da embratel ou devo colocar o IP da placa conectada ao modem embratel? ou nem preciso incluir essas duas linhas?
add dst-address=0.0.0.0/0 gateway=189.53.70.16 scope=255 target-scope=10 routing-mark=odd
add dst-address=0.0.0.0/0 gateway=189.53.70.16 scope=255 target-scope=10 routing-mark=even
