This sounds very familiar. I believe if you'll read the isdn spid1
command reference
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/
fdial_r/drfisl2.htm#wp1077028
You'll find that you can only bring up one B channel if you only have 1
spid and no LDN (for some isdn switches). If you'll add the LDN to the
isdn spid1 command, both channels will be able to come up.

Subject: PPP multilink - not getting the second BRI [IE lab 7]
Hi
Part of the question is to get both BRI channels together.
And i have the following configurations,
Rack4R5:
interface BRI2/0
ip address 163.4.45.5 255.255.255.248
ip router isis
encapsulation ppp
dialer map clns 33.0004.0004.0004.00 name Rack4R4 broadcast 2436155
dialer map ip 163.4.45.4 name Rack4R4 broadcast 2436155
dialer-group 1
isdn switch-type basic-ni
isdn spid1 4084370443
ppp authentication chap
ppp multilink --> Multilink is enabled
ppp multilink links minimum 2 -->so that both channels should come up
isis circuit-type level-2-only
dialer-list 1 protocol ip permit
dialer-list 1 protocol clns_is permit
Rack4R4:
interface BRI3/0
ip address 163.4.45.4 255.255.255.248
ip router isis
encapsulation ppp
dialer idle-timeout 0
dialer map clns 33.0005.0005.0004.00 name Rack4R5 broadcast 4370443
dialer map ip 163.4.45.5 name Rack4R5 broadcast 4370443
isdn switch-type basic-ni
isdn spid1 4082436155
ppp authentication chap
ppp multilink --------> mullink enabled
isis circuit-type level-2-only
Only R5 have the " ppp multilink links minimum 2" and that is beacuse
only R5 is allowed to dial and establish. There is no DDR on R4.
R5:
Sh ip in brief shows second channel is still down.
BRI2/0 163.4.45.5 YES NVRAM up
up
BRI2/0:1 unassigned YES unset up
up
BRI2/0:2 unassigned YES unset down
down
Any inputs are appreciated
Regards
