Hi all,

During the testing I found strange BMP issue. RFC 7854 describes several types of BMP messages, one of them is Stats Report (https://www.rfc-editor.org/rfc/rfc7854#page-13).

The FRR documentation (.https://docs.frrouting.org/en/latest/bmp.html#bmp-session-configuration ) explicitly says:
"

  • the following statistics codes are implemented:

    • 0: count of prefixes rejected

    • 2: count of duplicate prefix withdrawals

    • 3: count of prefixes with loop in cluster id

    • 4: count of prefixes with loop in AS-path

    • 5: count of prefixes with loop in originator

    • 7: count of routes in adj-rib-in

    • 8: count of routes in Loc-RIB

    • 11: count of updates subjected to RFC 7607 “treat as withdrawal” handling due to errors

    • 65531: experimental count of prefixes rejected due to invalid next-hop

    Note that stat items 3, 4 and 5 are specified to count updates, but FRR implements them as prefix-based counters.

"
The issue is that I do not see Stats Types 7 and 8 in the BMP message from FRR towards BMP collector (goBMP in my test setup):

There are only 7 statistic types and no statistic codes 7 and 8.

 Is this a bug or I missed something in BMP config ?

Here is the BMP config oof the FRR for the reference:

bmp targets ubuntu-BMP

  bmp stats interval 300

  bmp monitor ipv4 unicast pre-policy

  bmp monitor ipv4 unicast loc-rib

  bmp connect 10.30.131.101 port 5050 min-retry 30000 max-retry 3000 source-interface eth2

 exit


FRR1# sh ver

FRRouting 10.0_git (FRR1) on Linux(5.15.0-102-generic).


Thank you in advance for the clarification.


SY,
Boris
