I haven't seen that any other's posters have had this problem, which makes me think I may be missing something really basic in the configuration. Any help is greatly appreciated
I have MPPP configured on two routers' BRI interfaces with the load threshold set at one, so the second b channel should come up immediately. Two dialer maps are configured, each pointing to the same ip, using the different dial strings of the other router's two b channels: host Capetown interface BRI0 ip address 192.168.16.3 255.255.255.0 no ip directed-broadcast encapsulation ppp dialer idle-timeout 60 dialer map ip 192.168.16.1 name SanJose1 broadcast 384010 dialer map ip 192.168.16.1 name SanJose1 broadcast 384710 dialer load-threshold 1 either dialer-group 1 isdn switch-type basic-5ess isdn spid1 3847400001 384030 isdn spid2 3847400002 384750 ppp authentication chap ppp multilink host SanJose1 interface BRI0 ip address 192.168.16.1 255.255.255.0 no ip directed-broadcast encapsulation ppp dialer idle-timeout 60 dialer map ip 192.168.16.3 name Capetown broadcast 384030 dialer map ip 192.168.16.3 name Capetown broadcast 384750 dialer-group 1 isdn switch-type basic-5ess isdn spid1 3847000001 384010 isdn spid2 3847000002 384710 ppp authentication chap ppp multilink When a host off Capetown's E0 interface initiates traffic towards SanJose1, the first B channel comes up, but the second B channel never does. I've done a lot of debugging (dialer, q931, ppp negotiation) and staring blankly at it and I see what's happening, but I have no idea why, or how to correct it. What's happening is this: 1)Interesting traffic received 2)Dialer dials 384010 on the first B channel 3)Connection is made, PPP LCP, Authentication, and IPCP succeed. 4)Multilink bundle is sucessfully created with BRI0:1 as the only member 5)Load threshold is exceeded. 6)Dialer AGAIN TRIES TO DIAL THE SAME NUMBER - 384010 7)Q931 fails - message back from the isdn switch that the called line is busy (no surprise) 8)Dialer tries the other number - 384710 9)Error message that 2 dialers are already in use, no free dialers. (I take this to mean the dialer that originally called 384010, and the second dialer which again tried to call 384010) I have successfully MANUALLY got the second B channels to join the same multilink bundle and stay up, (Capetown)# isdn call int bri0:2 384710 so it seems to be just the one free dialer tieing itself up trying to setup a call on the second B channel to a number that the first B channel is already connected to. Thanks for any help. (The whole config on both routers is verbatim out of Cisco Sem 6 lab, other than using appropriate spids and dial strings).
