Can you grab some extra output?
show evpn
show evpn vni
show bgp l2vpn evpn import-rt
I'm assuming 10022 is the L2VNI here? If so, then the syntax below should be good. If not, could you replace "10022" with the proper VNID?
show bgp l2vpn evpn route vni 10022 mac 00:00:5e:00:01:22 ip 10.195.17.1
show bgp l2vpn evpn route vni 10022 mac 00:00:5e:00:01:22

None of the update debugs seem to mention the NLRI pointed out initially. Given the NLRI is in the BGP table already, I think we've made it past loop prevention.
From lab02:
Can you grab all the details for the routes in question from show bgp l2vpn evpn route type macip
?
Can you also get show evpn mac vni 10022
and show evpn arp-cache vni 10022
? (no specific mac/ip for either command)

On the 7.5.1 box, does ip nht resolve-via-default
fix the issue?
Yes it does!
Excellent! That's good to hear.
I don't recall offhand whether the difference in behavior (needed in 7.5.1, not needed in 7.4.1) was due to any bug fixes or explicit changes to default behavior.
@donaldsharp do you know what changes there might have been around ip nht resolve-via-default
(or nht resolution of BGP/EVPN next-hops) between 7.4.1 and 7.5.1?
@polychaeta autoclose in 2 days
@donaldsharp should we add ip nht resolve-via-default
into our production configs and upgrade to 7.5.1 or will the behaviour revert in a future version?
This issue will no longer be automatically closed.
@robmbrooks we haven't made a decision if/when such a behavior may change. If we do such a change it will be highlighted in the release notes. So I highly recommend checking the release notes before upgrading in a production environment.

frr since 7.5.1 failing to import vxlan default route
frr running on Centos 7, via rpms from rpm.frrouting.org. On frr-7.4.1 the route is valid and added to fdb. Once upgraded to frr-7.5.1 the route is not added, it can be seen, but is not marked valid.
[x] Did you check if this is a duplicate issue? [ ] Did you test it on the latest FRRouting/frr master branch?
To Reproduce
Upgrade frr from 7.4.1 to 7.5.1 with following config:
On a 7.4.1 host:
