Hi Group
if it was asked "r1 will authenticate r2 only when r2 call r1", should I
use callin or callout for r1. Please help. Config and debug below
r2#sr int s3/0:23
interface Serial3/0:23
ip address 172.16.12.2 255.255.255.0
encapsulation ppp
dialer map ip 172.16.12.1 name r1 broadcast 5678
dialer-group 1
isdn switch-type primary-ni
ppp callback request
ppp authentication chap
ppp multilink
end
r2#
r1#sr int s3/0:23
interface Serial3/0:23
ip address 172.16.12.1 255.255.255.0
encapsulation ppp
dialer callback-secure
dialer idle-timeout 20 either
dialer enable-timeout 5
dialer map ip 172.16.12.2 name r2 class CALLB broadcast 1234
dialer-group 1
isdn switch-type primary-ni
isdn protocol-emulate network
isdn T310 30000
ppp callback accept
ppp authentication chap callin
ppp multilink
end
"debug ppp authen" output of router r1
