Re: PPP with Multilink

Two things...

1. You have the PPP multilink link min 2 command in your config, so you
shouldn't have to use the dialer load-threshold to bring the second link up.

2. Try using the isdn test call int bri 0/0 "DN" command to verify layer 2
isdn call activities.

Here is a similar working config:

<snip>
interface BRI0/0
 ip address 183.1.45.5 255.255.255.248
 encapsulation ppp
 ip ospf demand-circuit
 dialer idle-timeout 180 either
 dialer map ip 183.1.45.4 name R4 broadcast 5272024
 dialer-group 1
 isdn switch-type basic-ni
 isdn spid1 51552720250101 5272025
 isdn spid2 51552720270101 5272027
 ppp authentication pap
 ppp pap sent-username R5 password 0 CISCO
 ppp multilink
 ppp multilink links minimum 2

</snip>
