Cisco CCNA / CCNP Certification Exam Tutorial: ISDN And Multilink PPP
ISDN is a large subject on both equally your Cisco CCNA and BCRAN CCNP examinations. While numerous ISDN topics appear to be straightforward, its the small print which make the main difference during the Test home and dealing with ISDN in generation networks. Configuring and troubleshooting multilink PPP is just one of the abilities youll have to pass both of these demanding exams.
With BRI, we’ve got two B-channels to carry facts, and equally of these Have got a 64-kbps capability.

Determine the edge at which the next b-channel need to start carrying info While using the dialer load-threshold command.
Permit’s say you wished the next b-channel to start carrying details when the 1st channel reaches 75% of capability. It might seem sensible that the command to take action can be dialer load-threshold seventy five… but it really’s not.
R1(config)#int bri0
R1(config-if)#ppp multilink
R1(config-if)#dialer load-threshold ?
<1-255> Load threshold to place One more call
The dialer load-threshold price is based on 255, not 100. To possess this command convey the line up at a specific percentage, multiply that percentage in decimal structure by 255. Down below, I multiplied 255 by .75 (75%) to arrive at 191.
R1(config-if)#dialer load-threshold 191 ?
