Hi, Qin Wu

Thank you for your kind comments and suggestions.

Please see my reply inline

[fuyu] The RFC7598 is referenced by the definition of RuleType

>2. Section 4.1, the 1st paragraph, last sentence Can you list

[fuyu] Yes, I will update it in more detail as : "MAP-E MIB is configurable 
on a per-interface basis, so it depends on several parts of the IF-MIB
by ifEntry [RFC2863]".

[fuyu] In the section 5 of RFC7597, it defines two types of mapping rules: 
Basic Mapping Rule (BMR) and Forwarding Mapping Rule (FMR). So we should accord with
this definition in RFC7597.
And in the section 4.1 of RFC7598, it defines F-flag to specify whether the rule is to be used
for forwarding (FMR).  If set, this rule is used as an FMR; if not set, this rule is a 
BMR only and MUST NOT be used for forwarding. And a BMR can also be used as
an FMR for forwarding if the F-flag is set.
So in the RuleType definition, it defines bmrAndfmr to specify this scenario.
I will update a description as above in section 4.1.1.

[fuyu] Yes, two kind of invalid packets In MIB module definition is mapSecurityCheckInvalidv4
and mapSecurityCheckInvalidv6, which are corresponding to two kind
of invalid packets described in section 4.1.2. I will update a clarify in the MIB definition.

>5.Section 6 does this document request IANA to assign new OID under

[fuyu] It request IANA to assign a new OID.


Thanks again for your review

Cheers
