All,
R1(bri)---{isdn}---(bri)R2
12.1(15) on both.
R1 is the callback client, R2 is the server
ppp callback configured using legacy config. (i.e. under the bri
interface)
R2 does not have a dialer map statement but only dialer string xxx
statement.
I noticed that R2 would NOT call back when dial string was configured.
it was when i changed it to "dialer map ...name R1 ..." that it was able
to callback.
ofcourse i was using a map class to enable callback server on R2. e.g.:
dialer map ip 171.1.1.8 name atlanta class dial1 81012345678901
dialer-group 1
ppp callback accept
ppp authentication chap
!
map-class dialer dial1
dialer callback-server username <-----
Note how:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/dial_r/
drdrd.htm#xtocid5
states this about the username keyword:
username: (Optional) Identifies the return call by looking up the
authenticated host name in a dialer map command. This is the default.
I tried with dialer callback-server dialstring option but no luck; R2 just
refuses to call back R1 unless there is a dialer map statement.
any help would be appreciated.
regards,
Omer
