In a two nexus 93180YC-EX (version 7.0(3)I7(3)) topology, configured with vxlan and evpn, I'm unable to get two hosts which are on two different vlan to communicate. L2 communication works but not l3
I have this error :
nexus2# sh bgp vrf tenant-1 l2vpn evpn 10.3.26.4

What is the right way to configure IRB routing in a fabric ?
Thanks a lot

in what device have you applied this change on Nexus2 ?
>> vlan 101
it is appplied to L2 brodacast domain vlan 101 not to SVI interface Vlan 101 . is it correct ?
vlan dedicated to the VRF (vlan 110) need to be added on both nexus.
Without vlan 101, the VRF Tenant-1 don't do his routing job
Yes, L2 broadcast domain vlan
Route-map permitall permit 10 set ip next-hop unchanged
Just wondering why do you have this, as when the routers are trying to do IRB, if you dont set the next hop properly, then the router at far end would advertising as it is, and while doing recursion since the far end hosts wont know where to forward the traffic it might fail the traffic forwarding.
