#Set the Dialer Idle Timeout.
#*Router(config-if)# '''dialer idle-timeout''' ''seconds''
#**The dialer idle timeout defaults to 120 seconds. It may need to be changed to a lower value to avoid excessive call charges.

#**The dialer map tells the interface what to do with interesting traffic
#**You do not need to enable broadcasts if your routing protocol does not need broadcast.
#**The dial string is the destination telephone number.
==Configuring Snapshot Routing==
#Configure a dynamic routing protocol.

#Configure the snapshot server
#*Router(config-if)#'''snapshot server''' ''active-time'' '''[dialer]'''

#**The dial-string is the destination snapshot server telephone number.

==Configuring B Channel Aggregation==
There are two types of B channel aggregation available on Cisco routers. This document was written using Multilink PPP.
*Cisco proprietary BOD uses a proprietary algorithm to calculate a load value and can only be applied outbound.
*Multilink PPP (MLP)uses a standards based algorithm and can be applied inbound, outbound, or either.
#Configure the load threshold that will trigger the use of the second B channel.
#*Router(config-if)#'''dialer load-threshold''' ''load'' '''[inbound | outbound | either]'''
#**The load argument can be any value between 1 and 255 (A threshold of 50 percent would be expressed as 128).
#**In the case of BOD, the directional keyword is not necessary as BOD can only be applied outbound.
#*Router(config-if)#'''ppp multilink'''
#**This step is only necessary when using MLP.
=Primary Rate Interface=
==Configuring Basic PRI==
'''This document assumes that a T1 controller has already been installed in the router.'''
#Configure the appropriate switch type
#*The switch type can be configured globally or on the interface. Global configuration will set all ISDN interfaces to that switch type, where as configuring the switch type on an interface will affect only that interface.

==Configuring B Channel Aggregation==
There are two types of B channel aggregation available on Cisco routers. This document was written using Multilink PPP.
*Cisco proprietary BOD uses a proprietary algorithm to calculate a load value and can only be applied outbound.
*Multilink PPP (MLP)uses a standards based algorithm and can be applied inbound, outbound, or either.
#Configure the load threshold that will trigger the use of the second B channel.
#*Router(config-if)#'''dialer load-threshold''' ''load'' '''[inbound | outbound | either]'''
#**The load argument can be any value between 1 and 255 (A threshold of 50 percent would be expressed as 128).
#**In the case of BOD, the directional keyword is not necessary as BOD can only be applied outbound.
#*Router(config-if)#'''ppp multilink'''
#**This step is only necessary when using MLP.

=Basic Rate Interface (BRI)=
This was set up in a lab enviroment using an Adtran Atlas 550 to simulate WAN connection. This document will configure an ISDN BRI connection with dial-on-demand routing (DDO), snapshot routing, and B channel aggragation.

==BRI Configuration With Dial-on-Demand Routing==
#Basic Router Configuration
#Configure the router to use the approiate ISDN switch types.
#*Router(config)# '''isdn switch-type''' ''type''
#**This configuration uses the basic-ni switch type. To learn about the other switch type, see [http://www.cisco.com/en/US/docs/ios/11_3/debug/command/reference/disdn.html ISDN Switch Types].
#Configure dialer list to identifiy intresting traffic.
#*Router(config)# '''dialer-list''' ''dialer-group-number'' '''protocol''' ''protocol-name'' '''permit | deny | list''' ''access-list-numeber''
#Configure BRI Interface with encapsulation and authentication settings.
#*Router(config)# '''interface''' ''interface-number''
#*Router(config-if)# '''ip address''' ''ip-address'' ''subnet-mask''
#*Router(config-if)# '''encapsulation ppp'''
#*Router(config-if)# '''ppp authentication chap'''
#Congigure a service profile identifier (SPID).
#*Router(config-if)# '''isdn spid''' ''spid-number'' ''local-dial-number''
#Set the Dialer Idle Timeout.
#*Router(config-if)# '''dialer idle-timeout''' ''seconds''
#**The dialer idle timeout defualts to 120 seconds. It may need to be changed to a lower value to avoid excesive call charges.
#Associate the interface to the already created dialer-list
#*Router(config-if)# '''dialer-group''' ''dialer-group-number''
#Configure the Dialer Map
#*Router(config-if)# '''dialer map''' ''protocol'' ''next-hop-address'' '''name''' ''hostname'' '''[broadcast]''' ''dial-string''
#**The dialer map tells the interface what to do with interesting traffic
#**You do not need to enable broadcasts if your routing protocol does not need broadcast.
#**The dial string is the destination telephone number.
==Configuring Snapshot Routing==
#Configure a dynamic routing protocol.
#*This document was created using RIPv2.
#Configure the snapshot server
#*Router(config-if)#'''snapshot server''' ''active-time'' '''[dialer]'''
#**the active-time argument is the amount of time in minutes that routing updates with be exchanged and must be the same between the server and the client.
#**The dialer keyword is an option to allow the client to dial up the server if there is no "interesting" traffic.
#Configure the snapshot client.
#*Router(config-if)#'''snapshot client''' ''active-time'' ''quiet-time'' '''[supress-statechange-updates] [dialer]'''
#**The quiet-time argument, like the active-time argument, is expressed in minutes and is generally equivalent to the active-time x3.
#**The suppress-statechange-updates option will prevent needless triggered updates in such situations as a line protocol changing states.
#*Router(config-if)#'''dialer map snapshot''' ''sequence number'' ''dial-string''
