The unique value which identifies this virtual router in the
Alcatel-Lucent SROS system. The vRtrID value for each virtual router
must remain constant at least from one re-initialization of the
system management processor (CPM) to the next. There will always
be at least one router entry defined by the agent with vRtrID=1
which represents the base transport router.
This object was obsoleted in release 6.0R15 and replaced with
