JUNOS 10.1 Network Interfaces Configuration Guide
NOTE: Ensure that the same IP subnet address is not configured on different dialer
interfaces. Configuring the same IP subnet address on different dialer interfaces can
result in inconsistency in the route and packet loss. Packets may be routed through
any of the dialer interfaces that have the same IP subnet address, instead of being
routed through the dialer interface to which the ISDN call is connected.
You can configure the following ISDN services logical interface properties:
The dialer interface cannot be configured:
For specific ISDN configuration information for dial-on-demand routing (DDR) and
adding Open Shortest Path First (OSPF) demand circuits to a Services Router, see
the JUNOS Routing Protocols Configuration Guide.
For general information about logical unit properties, see "Configuring Logical
Interface Properties" on page 373. For general information about
see "Protocol Family Configuration and Interface Address Statements" on page 181.
