# Network Service Virtual Link Configuration Mode Commands

The Network Service Virtual Link configuration mode is a sub-mode of the Network Service Entity - IP configuration mode. This sub-mode provides the commands and parameters to define the NSVL of the Gb interface between a BSS and an SGSN in a 2.5G GPRS IP network connection.
Upon entering this mode, the prompt should appear similarly to the following:

    [local]hostname(nse-ip-local-nsvl-<nsvl_id>)#
