This fixes 2 issues across a range of open tickets building upon patches created by others with modifications as requested by @VladimirKuk. The first issue this resolves is the status shown for remote vteps which in the fact that it is wrong makes debugging nearly impossible: ``` +------------+------------+-------------------+--------------+ | SIP | DIP | Creation Source | OperStatus | +============+============+===================+==============+ | 172.16.0.1 | 172.16.0.2 | EVPN | oper_down | +------------+------------+-------------------+--------------+ Total count : 1 ``` The VTEP is really up. Original PR for that is sonic-net#2080. Also fixes sonic-net/sonic-buildimage#10004 or at least the error message which hurts debugging. The next issue is in reachabiity across VXLANs. This fixes IP/MAC learning via ARP. The original PR for that is sonic-net#3216, however it appears it has its origins in sonic-net/sonic-buildimage#10050 which goes into greater detail about the issue itself. Also there is talk about it here kamelnetworks/sonic#9 as well as another similar patch here: kamelnetworks@02ee3e3 Fixes sonic-net#3216 Fixes sonic-net#2080 Fixes sonic-net/sonic-buildimage#10050 Fixes sonic-net/sonic-buildimage#10004 Signed-off-by: Brad House (@bradh352)

@VladimirKuk any idea if those test failures are actually a symptom of the patch itself? Or is it just common for things to fail in the tests from time to time? |
|
Tests do fail from time to time. |

What I did
This fixes 2 issues across a range of open tickets building upon patches created by others with modifications as requested by @VladimirKuk.
The first issue this resolves is the status shown for remote vteps which in the fact that it is wrong makes debugging nearly impossible:
The remote VTEP is really up.
Original PR for that is #2080.
Also fixes sonic-net/sonic-buildimage#10004 or at least the error message which hurts debugging.
The next issue is in reachabiity across VXLANs. This fixes IP/MAC learning via ARP. The original PR for that is #3216, however it appears it has its origins in
sonic-net/sonic-buildimage#10050 which goes into greater detail about the issue itself. Also there is talk about it here kamelnetworks/sonic#9 as well as another similar patch here: kamelnetworks@02ee3e3
Why I did it
Fixes #3216
Fixes #2080
Fixes sonic-net/sonic-buildimage#10050
Fixes sonic-net/sonic-buildimage#10004
How I verified it
Pulled into my private sonic-swss fork:
https://github.com/bradh352/sonic-swss/commits/202405-broadcom
Which is pulled in by my private sonic-buildimage fork:
https://github.com/bradh352/sonic-buildimage/tree/202405-broadcom
Which is then automatically built when changes are made. Then the uploaded asset of sonic-broadcom.bin is installed onto Dell S5248F and N3248TE switches and tested.
