Hello,
Thanks for reading my question.
I have an EVPN setup with 2x MX960 and 2x EX9200. We are having some problems with this setup (see other topic) so we decided to update our MX firmware from 14.2R5.8 to 14.2R7.5 and also upgrade the EX9200's in a later stage.
After the update of the first MX we noticed that EVPN has problems switching/routing traffic to the other devices.
L2 traffic is supported to flow from 34:6a:c2:47:48:70 to 00:30:17:0b:69:a8
The initial mac table of each device with the local mac learned:
user@MX> show bridge mac-table vlan-id 352
Bridging domain : VL352-net52_download, VLAN : 352
addresssss flags interface Index ID
34:6a:c2:47:48:70 D ae70.352
user@EX> show ethernet-switching table vlan-id 352
Ethernet switching table : 1 entries, 1 learned
name address flags interface Index ID
34:6a:c2:47:48:70 DC,SE - pip-14.740010000000 1048692 1048692
At this point i run a ping from the device connected to the MX to the device connected to the EX and MAC table is learned properly:
user@MX> show bridge mac-table vlan-id 352
Bridging domain : VL352-net52_download, VLAN : 352
addresssss flags interface Index ID
34:6a:c2:47:48:70 D ae70.352
00:30:17:0b:69:a8 DC 1048645 1048645
user@EX> show ethernet-switching table vlan-id 352
Ethernet switching table : 1 entries, 1 learned
name address flags interface Index ID
34:6a:c2:47:48:70 DC,SE - pip-14.740010000000 1048692 1048692
00:30:17:0b:69:a8 D,SE - ae11.352
This looks good, but only the first 1 or 2 pings worked. After that its a timeout.
-bash-4.1$ ping6 evs-web-01-352
PING evs-web-01-352(evs-web-01-352) 56 data bytes
64 bytes from evs-web-01-352: icmp_seq=1 ttl=64 time=1.84 ms
64 bytes from evs-web-01-352: icmp_seq=2 ttl=64 time=0.768 ms

Configuration has not changed and is still working fine on the other devices that have not been upgraded.
EVPN trace log does not show any irregular entries compared to the working devices.
Could anyone point me in the right direction?
