I connect two 2520 though Serial and ISDN,
R1(s3)---------------(s1)R2
|(bri0) |(bri0)
|______________________|
I use crossover cable to connect serial port. R1 is
DCE, R2 is DTE.
Configuration on R1:
interface Serial3
ip address 192.168.100.1 255.255.255.0
no ip route-cache
no ip mroute-cache
clockrate 64000
!
interface BRI0
ip address 192.168.200.1 255.255.255.0
encapsulation ppp
no ip route-cache
no ip mroute-cache
dialer idle-timeout 180
dialer map ip 192.168.200.2 name R2 broadcast
4082222222
dialer load-threshold 1 either
dialer-group 1
isdn switch-type basic-ni
isdn spid1 40811111111 4081111111
isdn spid2 40811111112 4081111111
ppp authentication chap
ppp multilink
On R2:
interface Serial1
ip address 192.168.100.2 255.255.255.0
no ip route-cache
no ip mroute-cache
!
interface BRI0
ip address 192.168.200.2 255.255.255.0
encapsulation ppp
no ip route-cache
no ip mroute-cache
dialer idle-timeout 180
dialer map ip 192.168.200.1 name R1 broadcast
4081111111
dialer load-threshold 1 either
dialer-group 1
isdn switch-type basic-ni
isdn spid1 40822222221 4082222222
isdn spid2 40822222222 4082222222
ppp authentication chap
ppp multilink
I can ping each other through both link.
Then I added backup interface bri 0 under s1 of R2.
Then I got:
R2# sh isdn stat
Global ISDN Switchtype = basic-ni
ISDN BRI0 interface
dsl 0, interface ISDN Switchtype = basic-ni
Layer 1 Status:
DEACTIVATED
Layer 2 Status:
Layer 2 NOT Activated
TEI Not Assigned, ces = 1, state = 1(terminal
down)
spid1 configured, spid1 NOT sent, spid1
NOT valid
TEI Not Assigned, ces = 2, state = 5(init)
spid2 configured, spid2 NOT sent, spid2
NOT valid
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 0 CCBs = 0
The Free Channel Mask: 0x80000003
Total Allocated ISDN CCBs = 0
When I shutdown the s1 of R2, nothing happened.
What's the problem?
Thank you for help.
Best Wishes,
Peng Zheng
