I was in the Cisco configuration Cookbook looking at backup interface and came up with some questions. Here are the configurations they gave:
Router 1:
!
hostname router1
!
username router1 password foo
username router2 password bar
isdn switch-type basic-ni1
!
interface Ethernet0
ip address 172.16.1.1 255.255.255.0
!
interface Serial0
ip address 192.168.1.1 255.255.255.0
backup interface BRI0
backup delay 5 30
!
interface BRI0
ip address 192.168.10.1 255.255.255.0
encapsulation ppp
dialer idle-timeout 300
dialer map ip 192.168.10.2 name router2 broadcast 5551212
dialer map ip 192.168.10.2 name router2 broadcast 5551313
dialer load-threshold 128
dialer-group 1
isdn spid1 40855578781010 5557878
isdn spid2 40855579791010 5557979
ppp multilink
ppp authentication chap
!
router igrp 1
network 172.16.0.0
network 10.0.0.0
!
dialer-list 1 protocol ip permit
!
---------------------------------
Router 2:
!
hostname router2
!
username router1 password foo
username router2 password bar
isdn switch-type basic-ni1
!
interface Ethernet0
ip address 10.10.10.1 255.255.255.0
!
interface Serial0
ip address 192.168.1.2 255.255.255.0
!
interface BRI0
ip address 192.168.10.2 255.255.255.0
encapsulation ppp
dialer idle-timeout 300
dialer map ip 192.168.10.1 name router2 broadcast
dialer map ip 192.168.10.1 name router2 broadcast
dialer load-threshold 128
dialer-group 1
isdn spid1 40855512121010 5551212
isdn spid2 40855513131010 5551313
ppp multilink
ppp authentication chap
!
dialer-list 1 protocol ip permit
!
------------------------------------------------------
My question is about this line:
dialer map ip 192.168.10.1 name router2 broadcast
dialer map ip 192.168.10.1 name router2 broadcast
They are the same line. What did they leave off here? If you type it in the way they have it you get:
adw-gw(config-if)#isdn spid2 1101070002
%isdn spid2 not allowed for 5ESS BRI custom
I assume this is caused by the incorrect line above. Seems funny they would say router2 since they are already on router2. Or is this cause due to me using the basic-5ess?
