Hi All,
Is there any way to configure multilink pppoe?
Dreamed scenario:
Customer has two ADSL connection end up on two different ADSL modems. Both connected to the router's two ethernet port.
The ISP take over the pppoe sessions from the DSL provider through l2tp and terminate all sessions on a virtual-template interface.
Challenge:
Bundle two pppoe sessions together.
I have seen similar config but with pppoa or when the router had atm interface, but in my case I'm looking for solution for ethernet interface on the cpe.
Thanks in advance,

Hi,
I think that unless the ISP configures MLPPP on his side (unlikely), that can't work.

Hi,
Fortunately I have some influence on the ISP side as well :)
How it should be configured on the ISP side?
Moreover how it can be achieved by Radius.
I believe special Radius attributes should be used to signal the router to use different virtual-template for this bundled link than the used by the "normal" users.
I think the client side is almost straightforward. The two ethernet interfaces connected to the two DSL modem should be configured with same pppoe-client dial-pool-number number and the ppp multilink should be enabled on the dialer.
A searched through the Cisco web but did not find a sample config.
Thanks in advance.

Hi!
We configured "ppp multilink" at the dialer-interface and bond the physical interfaces (for dsl-modems) to the Dialer-Pool (pppoe-client dial-pool-number X).
-> That works, but the problem is, it only works only ONE time (after the command "ppp multilink" was set to the Dialer-Interface).
If a bundled pppoe session is going down for any reason, the session comes never back to the mlp-bundle.
Any idea / any addtitional config necessary?
