Router 851 software versions

  Hello, I have a question regarding a router 851. I have tryed the configuration from an older post on my 851 router (i need pppoe confing) but It dosent work. I get this "% Invalid input detected at '^' marker." when i try to put this line "no ip dhcp use vrf connected". From what i saw this is because there are diffrent software versions acording to this: http://808techblog.com/netflow/2008/02/ but I dont have a solution.

My question is can I still configurate my router with this configuration: https://supportforums.cisco.com/message/3432601 if it has Version 12.4(15)T6?

This is my router running config:

In general I would think that the config should work ok with the different version of IOS code. When there are problems with things not working (especially things as fundamental as ppp) they are likely to be more related to differences in feature set or in licensing than to be about different versions of code.

The main problem that I notice is that interface Fastethernet4 which is your ppp interface is shutdown. Get that interface no shutdown and see what happens.

Take "debug ppp neg" and "debug ppp auth" with "term mon".

Note if you are replacing an ISp router you may need to wait some time with the cricuit off, of have ISP clear any MAC lock or cache.

Great! Thank you it works like a charm. It took me 2 days not to find the problem but i was searching in the wrong direction.

Thanks

I find that sometimes we are looking very hard expecting a complicated configuration problem when the real issue is so simple that we over look it.
