Creating a Leased Interface for Backup Service
For dial backup service to work, you need to configure the leased interface that
will use backup service. The leased interface is referred to as the primary circuit.
If the primary circuit fails, the router activates the backup connections to carry
data.
To configure the primary circuit, specify the type of leased interface and define the
data-link and network layer protocols.
For example, to create a primary serial interface on slot 2 connector 1 that
uses PPP and IP, begin at the box prompt and enter the following commands:
box# serial 2/1
serial/2/1# ppp
ppp/2/1# ip 192.122.32.1 mask 255.255.255.0
ip/192.122.32.1/255.255.255.0# cwc
box#
The last command,
cwc
, returns you to the box prompt.
To create a leased MCT1 line with frame relay and IP on slot 4 connector 1,
enter the following commands:
box# mct1 4/1
mct1/4/1# logical-line boston
logical-line/boston# frame-relay; service boston; pvc100
service/boston# ip 192.122.32.1 mask 255.255.255.0
ip/192.122.32.1/255.255.255.0# cwc
box#
