sdaHello guys.
I'm reading the RFC 6830 about the Lisp protocol.
I have a doubt about the Map replay about a EID overlapping prefix.
The RFC (Section 6.1.5.) said:
When an ETR is configured with overlapping EID-Prefixes, a
Map-Request with an EID that best matches any EID-Prefix MUST be
returned in a single Map-Reply message. For instance, if an ETR had
database mapping entries for EID-Prefixes:
10.0.0.0/8
10.1.0.0/16
10.1.1.0/24
10.1.2.0/24
A Map-Request for EID 10.1.1.1 would cause a Map-Reply with a record
count of 1 to be returned with a mapping record EID-Prefix of
10.1.1.0/24.
A Map-Request for EID 10.1.5.5 would cause a Map-Reply with a record
count of 3 to be returned with mapping records for EID-Prefixes
10.1.0.0/16, 10.1.1.0/24, and 10.1.2.0/24.
Note that not all overlapping EID-Prefixes need to be returned but
only the more-specific entries (note that in the second example above
10.0.0.0/8 was not returned for requesting EID 10.1.5.5) for the
matching EID-Prefix of the requesting EID.
To be honest, I cannot understand why a 10.1.5.5 request should receive 10.1.1.0/24 and 10.1.2.0/24.
The address not fall in these two address.
Thanks a lot and have a nice day.
