Hi, Is there anyone who tried this configuration? Is it working fine or not. I am trying to check it. The same webpage says it is possible to emulate PPPoA too. If anyone can input on this topic,that would be nice. TalentPk, Compy and many others were discussing about PPPoE emulation and PPPoA emulation... anyone can confirm it is possible with GNS3.

In fact, R1 and R2 is connected by their atm interface directly.


1. CPE Configuration (R2)

no ip routing
!
interface FastEthernet0/0
no ip address
bridge-group 1
!
interface ATM1/0
no ip address
bridge-group 1
pvc 2/200
encapsulation aal5snap
!
!
bridge 1 protocol ieee


2. R1 Configuration
Notes: The atm card on dynamips does not support pppoe, we use R4 to deal with pppoe packet. So ,R1 do only bridging.

no ip routing
!
interface FastEthernet0/0
no ip address
bridge-group 1
!
interface ATM1/0
no ip address
bridge-group 1
pvc 1/100
encapsulation aal5snap

3. Aggregation Router Configuration (R4)

vpdn enable

vpdn-group 1
accept-dialin
protocol pppoe

4. PPPOE client Configuration (R3)

Yes, if this has been done in dynamips, it can be easily replicated in gns3. are you facing any specific problem while doing this ? If yes, let me know.

if you download the video Talent kindly made, you can follow the step by step instructions

Thanks for replies,

TalentK videos shows PPPoE. But it required a DSL Connection from ISP, a modem and the Dynamips router act as PPPoE client to initiate PPPoE session. But in the above diagram it is saying that we can use ATM switches in Dynamips, Aggregation routers, and some routers act as simple modem by bridging and so on. So it is different, If anyone test the above diagram then please share with us. I tried to do it, but i couldnt find protocol pppoe under vpdn-group request dialin. Also regarding configuring ATM switches also I am a bit confused. I am keep trying here if found some positive signal i will share it.

i know what you are looking for, check the CCNP section with the similar Subject of this post.

TalentPk.

I tried in CCNP Section but couldnt find the same topic there. I mean the same scenario what I have copied here. I will try here anyway.

Thanks

You can use ATM Switches in GNS3 you need to configure just VPI/VCI settings properly under your ATM switches. make sure your destination and source VPI/VCI pair configured on ATM switch matches on the peering CPE routers
