This is my understanding on this subject after I did some research
It seems to me PPPoE is just a virtual-access link runs over ethernet-frame.
It is more from cable-headend Hub to multiple cable modem. ( cable modem
uses DVB/IPE technology, which works similar as ethernet mac-address)
So cable modem can dial in cable headend hub.
I can use dialer interface or virtual template.
I may have to make sure CDP run over this virtual link.( cdp disabled on VT)
for PPP negotiation.
The only unique requirement is a vdpn.
1) PPPoE over ethernet
Let's say R = remote station and H is cable headend Hub.
So topology is something like
R f0/0--cable modem( whatever) ------ f0/0 H
Based on my understanding, I come up with the following config ( never
chance to test)
R would need the following
vpdn enanle
vpdn-group 1( just a name)
request-dialin
protoocl pppoe
interface FastEthernet0/0
pppoe enable
pppoe-client dial-pool-number 10
Interface dialer 1
mtu 1402
ip address 10.1.1.1 <http://10.1.1.1> 255.255.255.0 <http://255.255.255.0>
dialer-group 20
dialer-pool 10
encap ppp
ppp authe chap
ppp chap host R
ppp chap password 0 R-password
dialer-list 20 protocol ip permit
H would need
username R password R-password
vpdn enanle
vpdn-group 1( just a name)
accept-dialin
protoocl pppoe
virtual-template 1
interface FastEthernet0/0
pppoe enable
Interface virtual-template1
mtu 1402
ip address 10.1.1.1 <http://10.1.1.1> 255.255.255.0 <http://255.255.255.0>
ppp authe chap callin
2) PPPoE over ATM
R A1/0--ATM pvc 200/200------ A2/0 H
Based on my understanding, I come up with the following config ( never
chance to test)
R would need the following
vpdn enanle
vpdn-group 1( just a name)
request-dialin
protoocl pppoe
interface ATM1/0
pvc 200/s00
pppoe-client dial-pool-number 10
Interface dialer 1
mtu 1402
ip address 10.1.1.1 <http://10.1.1.1> 255.255.255.0 <http://255.255.255.0>
dialer-group 20
dialer-pool 10
encap ppp
ppp authe chap
ppp chap host R
ppp chap password 0 R-password
dialer-list 20 protocol ip permit
H would need
vpdn enanle
vpdn-group 1( just a name)
accept-dialin
protoocl pppoe
virtual-template 1
interface ATM3/0
pvc 200/200
encapsulation aal5autoppp Virtual-Template1
Interface virtual-template1
mtu 1492
ip address 10.1.1.1 <http://10.1.1.1> 255.255.255.0 <http://255.255.255.0>
