Configuring Cisco Router 2900 for PPPoE

[joffreyjoffrey77]

I have DSL 8Mbps DL and 768kbps UL

The setup look like this:

Internet -> Modem -> Cisco Router -> Firewall -> Switch Core - > Multiple switches like sfe2000p

CiscoRouter: i use port gig0/1 for PPPoE and i use port gig0/2 for LAN static

Router port gig0/2 with 122.54.144.153/29 connected directly to Firewall port13 with 122.54.144.154/29

i want 122.54.144.153/29 will my default gateway

Please include no limit bandwidth,filter etc at router, Firewall will be DHCP Server and control the bandwidth, filtering etc and the client computer should get 8Mbps

There are many thread  on the matter as well documentation freely available on cisco.com, including example. These will give you a starting point from you you can always come back for specific questions or problems.

All you have to do is a search for pppoe client.

Post config obscuring sensitive data.

Here's my initial config

!

interface GigabitEthernet0/1

no ip address

duplex auto

speed auto

pppoe enable group global

pppoe-client dial-pool-number 10

!

interface GigabitEthernet0/2

ip address 122.54.144.153 255.255.255.248

duplex full

speed 1000

!

interface Dialer1

ip address negotiated

encapsulation ppp

dialer pool 10

ppp authentication pap callin

ppp pap sent-username xxxx password 7 xxxxx

ppp ipcp route default

!

ip forward-protocol nd

!

ip route 0.0.0.0 0.0.0.0 122.54.144.152

ip route 0.0.0.0 0.0.0.0 Dialer1

!

[paolo bevilacqua]

Try

interface dialer1

mtu 1492

ip tcp mss-adjust 1452

no ip route 0.0.0.0 0.0.0.0 122.54.144.152

no ip route  0.0.0.0 0.0.0.0 dialer 1

omg.. the last time i left this config its working fine

i can ping 4.2.2.2 while im router

but now.. i cant ping 4.2.2.2 the configuration is the same nothing change i just add your

mtu 1492

ip tcp mss-adjust 1452

there's something wrong or need to reboot/restart the hardware and configure it again..

coz i reconfigure it now by deleting interface dialer 1 and shutting down router port 1 and router port2

its still didn't work...

if i connect the modem on basic router like linksys.. it can give internet connection..it means my internet connection is active not down..

[paolo bevilacqua]

Check with "debug ppp neg" and "term mon" what happens. Sometime ISP locks to client MAC and it may take hours with the modem off to clear that.

However if your firewall supports PPPoE, and you don't want the router to perform NAT or other functions, there is no point in using the Cisco router at all.

[joffreyjoffrey77]

debug ppp neg

ppp protocol negotiation debugging is on

term mon

console already monitors

however i just want to learn about cisco.. its more fun..

i'm very interested of it

i want really to learn or someone hire me without salary just to teach me how to deal with cisco world

i can deal in 2 or 3 years..

i promise on that.. but in this world people would not do that.. they prefer to have expert people

[joffreyjoffrey77]

1.

mtu 1492 <-- may i know what is this.. and can i set higher number on this?

ip tcp mss-adjust 1452 <--- may i know what is this.. and can i set higher number on this to have more efficient speed

now i can ping 4.2.2.2 but

when i run speedtest to test my bandwidth it hangs

router message me this:

outbound cdp packet dropped, NCP not negotiated - what meaning of this?
