I upgraded a node from 1.2.3 to git, and now my node makes a flood of
outgoing BGP traffic. The traffic consists in messages that repeat the
same updates for a few routes. Here is one example (from tcpdump).
Update Message (2), length: 63
Origin (1), length: 1, Flags [T]: IGP
0x0000: 00
AS Path (2), length: 22, Flags [T]: 64731 64768 64677 64602 64602
0x0000: 0205 0000 fcdb 0000 fd00 0000 fca5 0000
0x0010: fc5a 0000 fc5a
Next Hop (3), length: 4, Flags [T]: 172.22.131.253
0x0000: ac16 83fd
Updated routes:
172.22.2.0/23
This exact message repeated more than 10 times in only about 20 seconds.
There are many more messages that also repeated more than 10 times in
the same 20 seconds.
