PPP multilink for ADSL

[taquiahmed]

I have two ADSL connections to one ISP both running on two different routers, can I configure PPP multilink on them for loadbalancing using one cisco router with 2 ADSL WIC card.

I have the same problem and I work around.

Hi,

I guess this is a real tough call, because to enable the MPPP (or PPP Multilink) both the sides of the links needs to be MPPP aware.

So that both links would get a single IP.

Not only that, ADSL is not a direct L-2 protocol, its combination of 2 or 3 Protocols, e.g. it might be PPPoE or PPPoA or PPPoAoE, hence making it very heavy and complex.

Though this doesn't mean that thats the end of the world, but, effectively you may find ways to do some load sharing in order to effectively use both the Links.

Please rate if it helps.

no ip address

no atm ilmi-keepalive

pvc 8/32

encapsulation aal5mux ppp dialer

dialer pool-member 1

interface Dialer0

ip address negotiated

encapsulation ppp

dialer pool 1

dialer-group 1

ppp authentication chap callin

ppp chap hostname xxxx

ppp chap password xxxx

ppp multilink
