def configBgpAsPathSegmentListNumber(self, routerId, asNumber, indexAndAsNumber):
        """
        Description
            Set BGP AS numbers in the route range. 
            If there are 5 AS# created under "Number of AS# In Segment-1", the asNumberList is
            the AS# that you want to modify for all route ranges (Device Group multiplier). 
            The indexAndAsNumber is the route range index and value: [3, 300].
            3 = the 2nd route range (zero based) and 300 is the value.

            NOTE! 
                Currently, this API will get the first Network Group object even if there are multiple
                Network Groups. Network Groups could be filtered by the name or by the first route range 
                address.  Haven't decided yet. Don't want to filter by name because in a situation 
                where customers are also using Spirent, Spirent doesn't go by name.

        Parameters
            routerId: The Device Group router ID where the BGP is configured.
            asListNumber: 1|2|3|...|6|..:  The AS# to modify.
                          (On GUI, click NetworkGroup, on bottom tab asPathSegment,
                           and on top tab, use the "Number of AS# In Segment-1" to set number of AS#1 or AS#2 or AS#3.)
            indexAndAsNumber: all|a list of indexes with as# -> [[1, 100], [3, 300], ...]

        Example:
            protocolObj.configBgpAsPathSegmentListNumber(routerid='195.0.0.2', 3, [[0,28], [3,298], [4, 828]])
