Re: loopback access

Can you ping the loopback from the source?

If not, you need to advertise the loopback into your routing domain.

Re: loopback access

yes I can ping the loopback, this is when I use my user/pass. it just dones not accepted .. but when I use someone else usr/pass I can access. the question is that the user/pass is global on the ntwk. I can access all the routers loopback on the ntwk w/ same usr/pass

Re: loopback access

So, you get a authentication prompt from the router when you telnet to its loopback but you get an authentication failure?

And you are able to authenticate to this same router but when you use any of its other Layer3 interface?

Interesting security policy you have there...

If you can, please share the router config.

Re: loopback access

I am so sorry , I will take that back , I am not able to access it at all even from other port.. but we have the same routers (14)or more. That I am able to access and like I said this is a global. but only my user/pass that can't access that loopback interface or any others. Do you think accessing it w/ other user/pass and give you the config will help

Thanks Edison
