Please see attached picture for network topolgy.
MLAG Config on spine1 (analog on spine2):
VXLAN Config on spine1:
BGP Config on spine1 (188.8.131.52 on Loopback2 only added for troubleshooting):
router bgp 64512
Communication works as expected when all switches are active (continuous ping from 172.16.0.10 to 172.16.0.11).
spine1(config-if-Et3)#sh ip route
What I noted: it seems the MAC addresses learned via remote VTEPs (VXLAN address-table) are not synced to other MLAG peer.
spine1#sh vxlan address-table
As soon as I disable et3 (DCI) on spine1, the communication stops working.
spine2#sh vxlan address-table
After a few minutes, spine1 obviously loses the entry for srv2 (spine2 still has ONLY the entry for srv1 but not for srv2):
spine1(config)#sh vxlan address-table
Unfortunatley I cannot do packet capture (not supported in GNS3 and monitor sessions in vEOS to CPU not working).
Any help is greatly appreciated!
