+ + 4.3 + DDR Configuration 
  + 4.3.6 + Dialer profiles 
+ + + + + + +
Legacy DDR is limited because the + configuration is applied directly to a physical interface. Since the IP + address is applied directly to the interface, then only DDR interfaces + configured in that specific subnet can establish a DDR connection with + that interface. This means that there is a one-to-one correspondence + between the two DDR interfaces at each end of the link.

+ Dialer profiles remove the configuration + from the interface receiving or making calls and only bind the + configuration to the interface on a per-call basis. Dialer profiles + allow physical interfaces to dynamically take on different + characteristics based on incoming or outgoing call requirements. Dialer + profiles can do all of the following:

+
    +
  • Define encapsulation and access + control lists
    • +
  • Determine minimum or maximum calls
    • +
  • Turn features on or off
    • +
+

Dialer profiles aid in the design and + deployment of more complex and scalable circuit-switched internetworks + by implementing a more scalable DDR model in Cisco routers and access + servers. Dialer profiles separate the logical portion of DDR, such as + the network layer, encapsulation, and dialer parameters, from the + physical interface that places or receives calls. +

+

Using dialer profiles, the following + tasks may be performed:

+
    +
  • Configure B channels of an ISDN + interface with different IP subnets.
    • +
  • Use different encapsulations on the B + channels of an ISDN interface.
    • +
  • Set different DDR parameters for the B + channels of an ISDN interface.
    • +
  • Eliminate the waste of ISDN B channels + by letting ISDN BRIs belong to + multiple dialer pools.
    • +
+

A dialer profile consists of the + following elements: +

+
    +
  • Dialer interface – A logical + entity that uses a per-destination dialer profile.
    • +
  • Dialer pool – Each dialer + interface references a dialer pool, which is a group of one or more + physical interfaces associated with a dialer profile.
    • +
  • Physical interfaces – + Interfaces in a dialer pool are configured for encapsulation + parameters and to identify the dialer pools to which the interface + belongs. PPP authentication, encapsulation type, and multilink PPP are + all configured on the physical interface. +
    • +
+

Like legacy DDR, dialer profiles activate + when interesting traffic is queued to be sent out a DDR interface. + First, an interesting packet is routed to a remote DDR IP address. The router + then checks the configured dialer interfaces for one that shares the + same subnet as the remote DDR IP address. If one exists, the router + looks for an unused physical DDR interface in the dialer pool. The + configuration from the dialer profile is then applied to the interface + and the router attempts to create the DDR connection. When the + connection is terminated, the interface is returned to the dialer pool + for the next call.
