EVPN-MPLS Why MAC and IP Pair is not apper?

tamatsushita · ‎12-08-2024

I have configured EVPN-MPLS using CSR100v with CML.
Why is the Type-2 information "MAC and IP" missing?
Shouldn't this entry contain the IP address?

[2][10.255.0.4:20][0][48][5254001F1F37][0][*]/20

I attached the configuration.

Because PE dont have idea about user IP'

Config static IP and try ping other IP and then check type2 mac-ip

Thank for reply.
I tried your advise, but mac-ip is still missing.

In your case, there is no need for IP-MAC type 2 routes.

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9600/software/release/17-14/configuration_guide/vxlan/b_1714_bgp_evpn_vxlan_9600_cg/configuring_evpn_vxlan_layer_3_overlay_network.html

You can check document above to see when such routes in use.
