ciscoMvpnMdtDataWildcardBits
1.3.6.1.4.1.9.10.113.1.3.2.1.4
Wildcard bits which when used along with data MDT range
address, give a pool of addresses to be used in a MVRF.
For example, if ciscoMvpnMdtDataRangeAddress is 239.1.2.0
and ciscoMvpnMdtDataWildcardBits is 0.0.0.3, the possible
data MDT addresses are 239.1.2.0, 239.1.2.1, 239.1.2.2
and 239.1.2.3.
Note that wild card bits should be right contiguous.
