could someone check my configuraiton? That'd be much appreciated!
I tried using CSR1KV and C8000v for home use with letting it act as PPPoE client and NAT gateway but with fail.
I almost searched for the whole internet for a resolution....When I use OpenWRT I just need to input my broadband username and password and then it works without any configuration, but for Cisco routers I tried many many times but failed
and I did some packet captures, modem already send c8000v PADO Active Discovery Offer, but Cisco router doesn't reply to modem at all. I put the capture file below:
and here's key configuration
interface GigabitEthernet1
ip address 10.0.0.8 255.255.255.0
ip nat inside
negotiation auto
!
interface GigabitEthernet3
no ip address
negotiation auto
pppoe enable group 1
pppoe-client dial-pool-number 1
!
interface Dialer1
mtu 1492
bandwidth 1000000
ip address negotiated
ip nat outside
encapsulation ppp
dialer pool 1
dialer idle-timeout 0
dialer persistent
dialer-group 1
ppp authentication pap callin
ppp pap sent-username username password 0 password
( I can make sure my ISP use PAP cleartext authentication because I checked it through openwrt capture )
!
ip route 0.0.0.0 0.0.0.0 Dialer1
!
ip access-list standard NAT_ACL
10 permit 10.0.0.0 0.0.0.255
!
dialer-list 1 protocol ip permit
Many thanks if someone take a look bro

Oh bro don't worry thanks for your reply!
no I didn't purchase any licenses. Isn't PPPoE included in IP Base?
If I need extra license to run PPPoE on C8000v , I would rather to buy a used C1111X-8P lol (I think it needn't any license to run PPPoE)

On what virtualisation infrastructure are you running the CSR1KV or C8000v?
Are you sure you have connected the link from your ISP to the GigabitEthernet3 of your CSR1KV or C8000v router?

Bro thank you for your reply.
I am pretty sure it is connected. It's KVM virtulization envionment, when I add virtio network port to openwrt the same way like I treat to C8000v, it just works with no problem.
Additionally, I tried to pass-thru the port that connect with ISP to C8000V but it didn't recognize, it has no driver (intel i225v)
C8000v supports virtio driver natively as per datasheet.

I think the ISP might be restricting the MAC address from which you are connecting. Can you configure on the 8000v interface Gi3 the same MAC address that you have on your OpenWRT:
interface GigabitEthernet3
mac-address <H.H.H>

Hello
try the following and test again:
conf t
license boot level network-advantage addon dna-advantage
end
reload

Yes bro I will try it, but why the router didn't prompt me anything if this function needs license to run....I am so confused about the licensing stuffs.

Hello
TBH not sure if you do require any licence, Ive just created a PPOE client on an 8000v and it works so maybe not - is it PPOE you are defiantly need to be using?
02-21-2025 09:01 PM
yes bro I need it work as PPPoE client. Want to use it as my gateway of my home.
I will try again or buy a used C1111X-8P cuz I like hardware product of Cisco....
Thanks again!

It didn't prompt you because the features you configured on the router didn't need a specific license. If that where the case, you couldn't configure the features because you wouldn't have the configuration commands available - like in the case of encryption for example.
The network-advantage and dna-advantage licenses mentioned by @paul driver are limited throughput perpetual licenses already installed on your router. You can enable them like Paul mentioned, but I don't think it will make a difference.

Yes bro thank you for your answer! I think you are correct, otherwise licensing will be really confusing

Hello,
can you post the output of:
debug ppp negotiation
debug pppoe event
debug pppoe packet

Did you get this to work? I am intrigued because I am using same line configs as my [working] C1111 and it does not work.
