Hi All
The current BMP Local-RIb draft doesn’t define what timestamp should be used in
Per-Peer header for BMP local RIB monitoring.
BMP RFC 7854 defines “Timestamp” in Per-Peer header as below:
Timestamp: The time when the encapsulated routes were received(one may also
think of this as the time when they were installed in the Adj-RIB-In),
expressed in seconds and microseconds since midnight (zero hour), January 1,
1970 (UTC). If zero, the time is unavailable. Precision of the timestamp is
implementation-dependent.
The above timestamp use doesn’t make much sense for local RIB monitoring case.
Proposal:
1. Since local RIB is not specific to a peer, the time stamp could be the
time when BMP RM message was created or sent to BMP collector.
1. Another option would be that the timestamp value be the time when this
prefix was installed in local RIB.
Otherwise the definition of “timestamp” would be the same as in RFC 7854. So,
something like this:
o Timestamp: The time when the encapsulated routes were installed in
The Loc-RIB, expressed in seconds and microseconds since
midnight (zero hour), January 1, 1970 (UTC). If zero, the time is
unavailable. Precision of the timestamp is implementation-
dependent.
Thanks
