    why do we need to create a sub interface 500 for ethernet 0 ?

  • bridgecarter

    and itzit possible for us to have multiple pppoe session on the router by having the same static route to different port like ip route e1 and ip route e2 ?

    • bridgecarter

      can load balancing occur by doing this ?

  • bridgecarter,
    1. Subinterface 500 is needed to “trunk” our e0/0 to BTU because we need to carry data vlan (500) and iptv vlan (600-config not shown here). BTU need to understand data packet tagged with vlan 500 for the internet packet.
    2.Yes you can have multiple PPoE sessions
    3. For redundancy, normally i will put a metric (ip route e2 10). If you didn’t put a metric, i believed the outgoing traffic will be load balanced. You’ll then need to adjust your NAT configuration:

    UNIFI1 to f0/0, UNIFI1 to f0/1

    access-list 10 permit
    route-map UNIFI1 permit 10
    match ip address 10
    match interface FastEthernet0/0
    route-map UNIFI2 permit 10
    match ip address 10
    match interface FastEthernet0/1
    ip nat inside source route-map UNIFI1 interface FastEthernet0/0 overload
    ip nat inside source route-map UNIFI2 interface FastEthernet0/1 overload

    i have no time to test the NAT config, but in theory it should work. To eliminate complex network setup, you can buy cheap TP-LINK load balancer for better traffic control.
