I am trying to use the "dialer persistent" option on a Cisco 802 with IOS 12.2.8T5 to keep an ISDN link up all the time yet the router redials very frequently (over 100 calls per day). This is a problem since the local CLEC charges ISDN calls on a per call basis (not per minute). Would appreciate any suggestions. Dialer configuration is similar to the one listed belows (dialer string, username, password changed).
ip unnumbered Loopback0
no ip proxy-arp
ip nat outside
no ip split-horizon
dialer pool 1
dialer remote-name myisp
dialer idle-timeout 0
dialer string 8005551212
dialer hold-queue 10
dialer load-threshold 3 either
dialer persistent delay 15
dialer persistent max-attempts 8
ppp authentication pap callin
ppp pap sent-username myuser.com password mypassword
Thanks for your suggestions. I will be doing some debugs later today.
It is a 128K ISDN link (2 channels) and over 100 calls per day are generated. Some calls last several hours and some last 15 to 20 minutes.
The IOS is 12.2.8T5 .
Is "ppp multilink" compatible with "dialer persistent" ? When multilink is enabled a "sho dialer in d1" shows "Dial reason: Multilink bundle overloaded" instead of "Dial reason: Persistent Dialer Profile".
