    building MPLS network


    dear all,
    i'm student that finished my final project,
    buliding VoIP over VPN MPLS (multiprotocol label switching).

    i have some problem, the design of my project like this :


    1. how can i make a routing table of the 5 computer wich set the router?
    2. how can i config zebra.conf?


    please help me...thanks.

    i have a routing table like this, but when i ping in LER A,
    there are some problem to connect to 203.150.8.1 and 203.150.8.2
    ---connection time out, (ping i run from LER A, but when i ceck from LSR 1, 203.150.8.1 to LSR 3, 203.150.8.2 it's OK, connected)

    Code:
    auto eth0
    iface eth0 inet static
