Configuring Dial Services
3-24
The configuration for this type of network is as follows:
The branch offices are configured for dial backup and are connected directly
to the regional router. They determine if the connection to the regional router
goes down and invoke the dial backup connection.
The circuits on Router 5, the recovery router, are configured as a demand
circuit group, with three circuits in the group. (Router 5 uses an existing
demand pool for the demand circuit group.) These circuits accept calls from
the remote routers configured with dial backup.
The Connection Mode for the circuits in the demand circuit group is set to No
Dial because the recovery router does not initiate connections. The remote
side of the connection must establish the connection first.
Router 5’s Caller Resolution Table contains entries for Routers 2, 3, and 4.
Each entry specifies the same demand circuit group.
In the example, if any of the branch offices detect a failure of the regional router,
any one of them can bring up a dial backup connection and place a call to the
recovery router. Once the connection is made, data can continue to go across the
network.
Implementation Notes Specific to Bandwidth-on-Demand
The following sections detail bandwidth-on-demand operation.
PPP Multilink
Multilink is a feature of PPP that you can enable for individual PPP links. Links
are logical communication channels between two routers. Typical links include
one ISDN B channel, one dial-up modem connection, and a leased 64 Kb/s line.
Multilink enables you to:
Group lines of different speeds
Distribute traffic more evenly among the lines
Maintain packet sequence
Monitor traffic volume (in the context of bandwidth-on-demand)
