Based on the configuration and log messages, the issue lies with the leaf node not being configured for the family evpn NLRI. The spine node is configured for EVPN as indicated by 'family evpn;' in the configuration. However, the log message shows that the spine is receiving an unsupported capability notification from the leaf node, particularly 'MP capability afi 1, safi 1 <inet-unicast>' which indicates that the leaf node is trying to establish a BGP session with inet-unicast instead of evpn. Therefore, the correct issue is that the leaf node is not configured for the family evpn NLRI.
For Spine and Leaf connection, you only need family evpn and that's it. So the logs reveals spine mentions it received leaf's open message with NLRI capacity as inet-unicast, the leaf can keep it that way but most importantly, the leaf must have the capacity to support evpn family, so the answer is D.
b is correct for me. the log shows spine does not support inet nlri, and there’s no proof that leaf does not support evpn nlri
AFI 1 / SAFI 1 - ipv4
B. The spine node is not configured for the family inet NLRI. family inet == inet-unicast. 10.30.100.6 is sending notification and tearing down the BGP session because address family has not been configured.
When using EVPN in a Spine and Leaf network architecture, you only need to configure the family EVPN protocol on the Spine and Leaf switches. This will allow the switches to exchange MAC addresses and other relevant information required to establish Layer 2 connectivity between devices.
the SPINE is telling the leaf of an unsupported option. This means that the SPINE is missing unicast
