Hi Community,
i moved my config from CHR or RB5009 or L009 to CRS520.
The EVPN Connections don’t work. Is there a Hardware/CPU related issue?
On the CHR and RB and L009 everything runs fine.
But on the CRS520, i don’t get it running.
Best Regards!
YAN
i could test the Config/Setup on following Devices:
Leaf1 = ROSE (RDS2216-2XG-4S+4XS-2XQ)
Leaf2 = ROSE (RDS2216-2XG-4S+4XS-2XQ)
Spine1 = CRS520 (CRS520-4XS-16XQ)
with that setup, everything works! 
allegedly because the spine don’t need EVPN.
Maybe the CRS is not able to do EVPN.
Meanwhile i tested the v7.21.beta7 on CRS520-4XS-16XQ as Leaf and Spine. PING not possible.
