hi all,
I have a 2610 router with a four port isdn module. All the four are configured for multilink PPP to dial to ISP for internet access. Recently i have noticed that inspite of the dialer showing UP, I cannot ping any public ips. Even the sh ip int brief command also shows the dynamic ip address acquired by the ISP with line/protocol up.
Generally after i reboot,the problem gets solved.
ISP end there is no problem.
Router has 8MB flash and 32MB DRAM.
Will upgrading the router memory help ????
Thanks
Rgds

Hello,
what happens if you issue the clear interface bri command ? Is connectivity ok after that ? This might be an IOS bug, what IOS version are you using ?

thanks for the reply
The link immediately drops after i issue the clear int dialer command. And it dials again and gets connected. Generally I can ping the ISP DNS after this. The IOS is IOS (tm) C2600 Software (C2600-I-M), Version 12.0(7)T,

Hi,
First, are you able to ping to your next hop first provided your dial interface UP. What's the idle timeout are u having?
