[c-nsp] pppoe-link

[K bharathan]

| upstream ISP |------------>| Fibre Link |---------->| downstream ISP (gw
rt) |

Fibre link (1 line) is divided into 3 VLANS
1 vlan for internet bandwidth (wan ip from upstream ISP
1 vlan for DSL bandwidth (wan ip from upstream ISP)
1 vlan (l2tp link) for PPPOE from their VPLS network; no wan ips on this;

the link terminates at downstream ISP gw router

problem: there is no wan ip on the PPPoe link how a PPPoe server can  be
answering the DSL client; how can this particular link can be  connected to
the downstream ISP network; anybody has got any ideas ?
thanks
