Hi,
I have a question. If I configure my VTEPs just with L2VNIs (No vrfs, no svi, no l3vnis) to get reachability between hosts in the same subnet (just as an old switching environment approach), which is basically a MAC-MAC approach and no MAC-IP approach. Why in my BGP EVPN table im getting MACs + 0.0.0.0 routes and no IPs of the hosts as when there ir ARP resolution BGP EVPN will store that IP address in its table? With other vendors this is true:
Cisco BGP EVPN table all MACs with 0.0.0.0 (default gateway is outside the fabric)
Network Next Hop Metric LocPrf Weight Path
Route Distinguisher: 1.1.1.1:32777 (L2VNI 1000010)
*>l[2]:[0]:[0]:[48]:[0000.0c9f.f00a]:[0]:[0.0.0.0]/216

100.100.100.100 100 32768 i
With other vendor in the same approach (no vrf, no SVI, no nothing, just L2VNIs) I obtain the IP address of the end host + its MAC and not 0.0.0.0 just like Cisco
VLAN MAC address Active source Timestamp IP address
100010 [omitted] 00:01:00:00:00:00:00:00:01:00 Feb 07 22:46:07 192.168.10.1
100010 [omitted] 00:02:00:00:00:00:00:00:01:00 Jan 20 20:45:51 192.168.10.2
Can someone explain me why or if im doing something wrong? I have reachability but its just wondering why I dont see IP address in that L2VNI whilst in another vendor I do...
Thanks!!!
