Table of static routes configured on this entity.
The object definitions and indexing for this table are chosen to closely
align with the IP-FORWARD-MIB's ipCidrRouteTable.
This table serves three purposes:
1. Provide the means for configuring static routes.
2. Provide an efficient view of static routes (otherwise they must be
observed by traversing the entire routing table).
3. Provide view of static routes configured on network interfaces that
are currently inactive. (In this implementation, static routes
configured on inactive interfaces are not visible in the routing
table.)
