I've been trying to figure out what makes MLAG implementation in a vxlan enviroment different from other more 'regular vlan' implementations. The user guide suggests that the isc link gets turned into an ospf routed link, but it doesn't go into detail on how this impacts the rest of the mlag setup.
I've gotten this far with my configuration so far, it's working for traffic to and from vmware-hosts, however when connecting to other existing l2 enviroments strange things seem to happen with broadcast packets, and a switch-loop like scenario seems to appear.
I'm at wit's end on what the correct implementation of mlag and vxlan is supposed to be, I'm attaching the configuration I've done so far in hopes more experienced minds can figure out what I'm missing.
The configuration example omits ospf information, since I have done no such configuration in regards to mlag.
# Setting the same IP on both switches ensures both identify as the same
# vxlan endpoint
# Mlag peer creation: # Both:

OSPF router-ID and local address is configured as a secondary-IP on the vlan loopback. This is to keep the number of OSPF interfaces down so we can still keep under the limit imposed on the Advanced Edge licence.
