4. Updating Implementations

There are several general classes of change that are required.

The first and most major change is that most of the previous objects have different object IDs and additional indexes to support the possibility of different address types. The general counters for IP and ICMP are examples of this. They have been moved to the ipSystemStatsTable and icmpMsgStatsTable, respectively.

The second change is the extension of all address objects to allow for both IPv4 and IPv6 addresses and the addition of an address type object to specify what address type is in use.

The third change is the addition of several new objects to the replacement for a previously existing table such as ipNetToPhysical.

The fourth change is the addition of completely new tables such as ipIfStatsTable and ipDefaultRouterTable. The first is based on the previous statistics groups, while the second is completely new to this MIB.
