Unanswered Question
Feb 7th, 2007

Hi,

I cannot connect to my isp. they revamped there system today and say nothing has changed.

I do a "show ip interface brief" and all phsical layers are up.

Router#sh ip int br

Interface IP-Address OK? Method Status Protocol

ATM0 unassigned YES NVRAM up up

Dialer0 unassigned YES NVRAM up up

Ethernet0 10.254.0.100 YES manual up up

Virtual-Access1 unassigned YES unset up down

so i check my ppp debug negotiation to see whats going on with the connection.

For refernce I enclose cisco links/explanations for this exact debug ppp otput.

-------- start of link & info ---------------

Cisco DSL Router Configuration and Troubleshooting Guide - PPPoA Troubleshooting

http://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_example09186a008071a69d.shtml#l2c

No Response from Your ISP

In this output there are only O packets, which are outbound packets. In order to successfully negotiate PPP, there should be an I inbound packet from your ISP for each O packet sent. If packets are incrementing inbound but you do not see I packets, contact your ISP in order to verify the packets that are sent to the Cisco DSL Router.

-------- end of link & info ---------------

so it seems what is happening is exactly as described. I have talked to ISP and they have blown me off.

they are a bigtime cisco partner ( https://www.tiscali-business.co.uk/partners/cisco.html )and they don't want to know about end users with cisco routers.

a speedtouch adsl modem is working so that is their demarcation point.

i'm hoping for some feedback from the professionals that will help me back on line again the cisco way.

kind regards and thanks

Phil

turns out settings !!!HAD!!! changed on the service providers end, though nobody will confirm it at tiscali.

Only a little thing like their pvc encapsulation method. I not surprised nobody on their end noticed this.

pvc 0/38

encapsulation aal5snap

protocol ppp dialer

dialer pool-member 1

!

IS NOW:

pvc 0/38

encapsulation aal5mux ppp dialer

dialer pool-member 1

!
