using PPP multilink with DSL services

hello,

i tried to find some docs with regards to using PPP multilink with DSL circuits... but i didn't find anything or maybe i looked in the wrong place.

this is what i want to do:

- 2 or 3 dsl circuits tied together from the same cpe with diff physical xdsl interfaces

- dslam 6130 or 6160

- uac 6400

thank you,

mihai

Re: using PPP multilink with DSL services

YES..it is possible as long as the adsl links are from the same cpe (may be two adsl wics). Here is the way to configure on 6400 with two different pvc from the same cpe/username for pppoa.

interface ATM3/1

no ip address

no atm ilmi-keepalive

dsl linerate AUTO

no fair-queue

!

interface ATM3/1.1 point-to-point

pvc 5/202

encapsulation aal5mux ppp dialer

dialer pool-member 1

!

interface ATM3/1.2 point-to-point

pvc 5/203

encapsulation aal5mux ppp dialer

dialer pool-member 1

!

interface Dialer1

ip address 192.168.117.2 255.255.255.0

encapsulation ppp

no ip route-cache

no ip mroute-cache

dialer pool 2

no cdp enable

ppp authentication chap

ppp multilink

no ppp multilink fragmentation

Re: using PPP multilink with DSL services

hello,

thank you for your reply.

here are a couple of things:

- i'm not sure how you can use "dsl linerate AUTO" on the NRP card of a UAC6400.

- i followed the ideea with dialer-pool - i don't have dialer set of commands under the point-to-point interfaces on a NRP card in a UAC 6400

- my NRP - UAC 6400 - is c6400r-g4p5-mz.122-2-B5-S2.bin

The config you send seems like the config for the CPE box ..... my problem is on the other end ...

In my understanding the dialer set of commands are related to the CPE side of the network - but still at the other end I have to have something that knows what to do with those incoming ppp frames and to put them back together.

thank you,

mihai iancu

ps: it's in your message ... "Here is the way to configure on 6400 ..."

ok ... i got it working ... now i'll go forward with my tests .... because guess .... i need to transport ethernet frames .... on top of the ppp ... don't ask me why :))) .... i just have to do it :)
