I configure ISDN, it works before, but now I can not
make it work.
Below are config:
R4:
hostname Rack06R4
username Rack06R5 password 0 cisco
interface BRI0
ip address 145.45.45.4 255.255.255.240
encapsulation ppp
dialer map ip 145.45.45.5 name Rack06R5 broadcast
5556001
dialer map ip 145.45.45.5 name Rack06R5 broadcast
5556002
dialer-group 1
isdn switch-type basic-ni
isdn spid1 50355550010101
isdn spid2 50355550020101
cdapi buffers regular 0
cdapi buffers raw 0
cdapi buffers large 0
ppp authentication chap callin
--------------
on R5:
hostname Rack06R5
!
aaa new-model
aaa authentication ppp default local
aaa authorization network default local
username Rack06R4 password 0 cisco
interface BRI0
ip address 145.45.45.5 255.255.255.240
encapsulation ppp
isdn switch-type basic-ni
isdn spid1 50355560010101
isdn spid2 50355560020101
cdapi buffers regular 0
cdapi buffers raw 0
cdapi buffers large 0
ppp authentication chap
-------------------------------
When I tried sh isdn status on both, I got:
Global ISDN Switchtype = basic-ni
ISDN BRI0 interface
dsl 0, interface ISDN Switchtype = basic-ni
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 109, Ces = 1, SAPI = 0, State =
MULTIPLE_FRAME_ESTABLISHED
TEI = 110, Ces = 2, SAPI = 0, State =
MULTIPLE_FRAME_ESTABLISHED
TEI 109, ces = 1, state = 5(init)
spid1 configured, no LDN, spid1 sent,
spid1 valid
Endpoint ID Info: epsf = 0, usid = 2, tid
= 1
TEI 110, ces = 2, state = 5(init)
spid2 configured, no LDN, spid2 sent,
spid2 valid
Endpoint ID Info: epsf = 0, usid = 4, tid
= 1
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 0 CCBs = 0
The Free Channel Mask: 0x80000003
Total Allocated ISDN CCBs = 0
-----------------
But when I tried debug on Rack06R4, I got:
00:39:26: BRI0: wait for isdn carrier timeout, call
id=0x803F
00:39:26: BR0 DDR: Dialing cause ip (s=145.45.45.4,
d=224.0.0.5)
00:39:26: BR0 DDR: Attempting to dial 5556001
The calling number is correct. But can not connect to
Rack06R5.
What's the possible reason?
How to debug this?
Thanks for help.
