The value of the object svcVRouterId specifies, for a IES
or VPRN service the associated virtual router instance
where its interfaces are defined.
This object has a special significance for the VPRN
service as it can be used to associate the service to a
specific virtual router instance.
If no routing instance is specified or a value of zero (0)
is specified, the agent will assign the vRtrID index value
that would have been returned by the vRtrNextVRtrID object
in the TIMETRA-VRTR-MIB. The agent supports an SNMP SET
operation to the svcVRouterId object only during
row creation.
