Currently you can not configure two routers to communicate using PPPoA
for SVCs.

Subject: Re: Configuring PPP over ATM SVCs
Hi Gladston,
Please let me know if you have configured "pvc 0/16 ilmi"
and "pvc 0/5 qsaal" under main ATM interface of R9.
Also, after configuring the above commands try using "show
ilmi-status".
HTH,
Mihai

Any feedback appreciated.
My lack of experiency using this feature make me think I could test it
pinging 1.1.4.9, but Cisco example does not configure remote ATM SVC
address.
How is the remote SVC address acquired on real use of this feature?
Is it possible to simulate it on lab?
Here the configuration I used:
r6#sh run
interface ATM1/0.369 multipoint
atm nsap-address 47.00000000000000000000000A.466666666666.00
!
svc PPPoATM
encapsulation aal5auto
protocol ppp Virtual-Template2
!
interface Virtual-Template2
ip address 1.1.4.6 255.255.255.0
r9#sh run
interface ATM1/0.369 multipoint
atm esi-address 499999999999.00
!
svc PPPoATM
encapsulation aal5auto
protocol ppp Virtual-Template2
!
interface Virtual-Template2
ip address 1.1.4.9 255.255.255.0
I tried this (may look crazy; as I did not find any example I tried to
force a remote ATM SVC address):
r6#sh run int atm 1/0.369
Building configuration...
Current configuration : 270 bytes
!
interface ATM1/0.369 multipoint
atm nsap-address 47.00000000000000000000000A.466666666666.00
!
svc nsap 47.00000000000000000000000A.499999999999.00
protocol ip 1.1.4.9 broadcast
!
!
svc PPPoATM
encapsulation aal5auto
protocol ppp Virtual-Template2
!
end
r9#sh run int atm 1/0.369
Building configuration...
Current configuration : 241 bytes
!
interface ATM1/0.369 multipoint
atm esi-address 499999999999.00
!
svc nsap 47.00000000000000000000000A.466666666666.00
protocol ip 1.1.4.6 broadcast
!
!
svc PPPoATM
encapsulation aal5auto
protocol ppp Virtual-Template2
!
end
I tested PPP over ATM with PVC on the same devices, it works fine. The
problem is just to test PPP over ATM using SVC.
Any feedback appreciated.
