I posted a similar question awhile back, but found an interesting issue
working on dialer watch and profiles last night...it appears that when you are
using dialer watch in profiles that you can get somee strange results. The
dialer idle-timeout that is suppose to check the line, actually drops the link
and redials. Then, once it dials the line and comes up....and then, the
primary comes back, the backup never drops the line and reverts back to the
primary.
However, if you take the same configuration information and move it under the
BRI interface and eliminate the profile, everything is happy. This may be
related to the code of 12.2, but not sure.
Here is what the configs look like:
The one that works:
interface BRI0
bandwidth 128
ip address 10.11.24.2 255.255.255.252
encapsulation ppp
no ip route-cache cef
no ip route-cache
dialer map ip 10.11.255.252 name HOST broadcast 5551212
dialer watch-group 10
isdn switch-type basic-ni
isdn spid1 55555555550101
isdn spid2 66666666660101
no fair-queue
no cdp enable
ppp authentication chap callin
ppp multilink load-threshold 10 either
dialer watch-list 10 ip 10.11.255.252 255.255.255.252
Here is the one that did not work cleanly:
interface BRI0
bandwidth 128
no ip address
encapsulation ppp
no ip route-cache cef
no ip route-cache
dialer pool-member 10
isdn switch-type basic-ni
isdn spid1 55555555550101
isdn spid2 66666666660101
no fair-queue
!
interface Dialer1
bandwidth 128
ip address 10.11.24.2 255.255.255.252
dialer watch-group 10
encapsulation ppp
dialer pool 10
dialer remote-name HOST
dialer idle-timeout 60
dialer string 5551212
ppp authentication chap callin
ppp multilink load-threshold 10 either
!
dialer watch-list 10 ip 10.11.255.252 255.255.255.252
In researching the dialer watch, I did notice that you need to have the same
route in the watch list (as the dialer map). However, I cannot find a command
that is similar to the dialer map (this may relate to the problem). Also, I
cannot find a good example with the profile and dialer watch used together.
Any thoughts or ideas on this weird one?
