2. Abstract IP TUNNEL MIB(RFC4087) provides tunnel provisioning capability by SNMP. But it is not enough to support modern tunnel protocol such as 6rd[RFC5969] and MAP[draft- ietf-softwire-map]. The document describes extention of IP TUNNEL MIB[RFC4087] to support 6rd[RFC5969] and MAP[draft-ietf- softwire-map].draft- ietf-softwire-mapdraft-ietf- softwire-map

3. tunnelIfXTable DS-lite B4 could support IP Tunnel MIB MAP-T has compatibility with 464XLAT. So if extension tunnel MIB,does not need any additional MIB.

4. Proposal background MAP supports both MAP-T and MAP-E MAP uses same algorithm between E and T MAP has compatibility with DS-LITE and 464XLAT Both MAP and 6rd using SAM Tunnel MIB are IP version-agnostic object Any comments?
