Just to set the agenda: the definition of the address mapping table entry:
natv2AddressMapEntry OBJECT-TYPE
SYNTAX Natv2AddressMapEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"Mapping from internal to external address."
INDEX { natv2AddressMapInstanceIndex,
natv2AddressMapInternalRealm,
natv2AddressMapInternalAddressType,
natv2AddressMapInternalAddress }
::= { natv2AddressMapTable 1 }
Natv2AddressMapEntry ::=
SEQUENCE {
natv2AddressMapInstanceIndex Natv2InstanceIndex,
natv2AddressMapInternalRealm SnmpAdminString,
natv2AddressMapInternalAddressType InetAddressType,
natv2AddressMapInternalAddress InetAddress,
natv2AddressMapExternalRealm SnmpAdminString,
natv2AddressMapExternalAddressType InetAddressType,
natv2AddressMapExternalAddress InetAddress,
natv2AddressMapSubscriberIndex Natv2SubscriberIndexOrZero
}
Now some example numbers:
natv2AddressMapInstanceIndex = 1
natv2AddressMapInternalRealm = "DS-Lite Group 5"
natv2AddressMapInternalAddressType = ipv6(2)
natv2AddressMapInternalAddress = 2001:db8:0:1::1
natv2AddressMapExternalRealm = "global4"
natv2AddressMapExternalAddressType = ipv4(1)
natv2AddressMapExternalAddress = 192.0.2.1
natv2AddressMapSubscriberIndex = 487231
This entry would be indexed by the combination of
{ 1, "DS-Lite Group 5", ipv6(2), 2001:db8:0:1::1 }

In the first place, you replace the IPv4 --> IPv4 mapping with
{IPv6, IPv4} --> IPv4 mapping. See Section 5.6 of RFC 6333.
I understand that, but I don't see how the proposed MIB text does that.
Beyond that, the text I gave refers to a single mapping in the address map
table. For different external IPv4 external addresses, you would be looking
at different mapping instances.
Can you please give an example with numbers showing how a DS-Lite address
mapping would be represented in the MIB?
Thanks,
Simon
