WAE choses wrong loopback when building its IGP.

OXYD

Hey!
It’s a longshot but let’s see if we have any WAE experts here.

I have a problem with WAE and it’s not solved in latest release 7.6.0. Does anyone have an idea on how to solve this?
In our network we have started to use Arista nodes. It hasn't been a big problem until now when we got more Arista and added an extra loopback interface.
Problem is that WAE gets confused on what's the correct router-id on some Arista routers.
It creates its IGP DB from a Cisco device but then thinks it’s the same loopback on several of the Arista nodes and then removes them from its IGP DB.

Output from Cisco seed router clearly states the router-id correctly.
RP/0/RP0/CPU0:x-b6#show isis database verbose x-b5
...
Router ID: 192.168.0.1
Hostname: x-b5
IP Address: 192.168.0.3
IP Address: 192.255.255.255
IP Address: 192.168.0.1
IP Address: 192.168.0.2
...
output from wae 6.4.16 is similar as for 7.6.0

Anyone that has a clever way around this?
