利用兩台Mikrotik Router的switch晶片橋接IPTV與網路

 在家中橋接網通設備,若中間置入台MOD(IPTV,透過Modem multicast發送)是個很頭痛的問題.
 但若是分享器或交換器支援vlan,就容易的多.
 
 以下是用RB450G+RB750GL建置:
 
  因這兩台Router的內部交換機晶片可處理vlan標記,
 所以就不再使用軟體的bridge ,而是用switch chip.
 
 複製代碼#RB450G
/interface bridge add name=bridge
/interface bridge port
add bridge=bridge interface=ether1 hw=yes
add bridge=bridge interface=ether2 hw=yes
add bridge=bridge interface=ether3 hw=yes

add bridge=bridge interface=ether5 hw=yes
/interface ethernet switch port
