In Cisco SD-Access, the border node serves as the gateway for communication between the fabric (SD-Access domain) and external networks (nonfabric devices). It is essential for allowing traffic to flow in and out of the fabric. The control plane node, on the other hand, maintains the full mapping database of RLOC (Routing Locator) to EID (Endpoint Identifier), which is crucial for the fabric’s routing and forwarding decisions. References: Cisco SD-Access Solution Design Guide

The exhibit shows that R1 has a BGP neighborship with a router at IP address 192.168.50.2. The command set that is applied between the iterations of show ip bgp 2.2.2.2 is the one that would cause a RIB-failure. A RIB-failure occurs when a route is not installed in the Routing Information Base (RIB) due to a routing issue. In this case, removing the specific static route to the neighbor with no ip route 192.168.50.2 255.255.255.255 Gi0/0 would cause theBGP session to drop and result in a RIB-failure for the route to 2.2.2.2, which is what we observe in the exhibit. References := For more information on BGP neighborship and RIB-failure, refer to the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) course materials, specifically the sections on BGP routing and troubleshooting.

Enabling P2P (Peer-to-Peer) Blocking Action is crucial in a WLAN setup to prevent wireless clients from communicating directly with each other, ensuring that all traffic is routed through the WLAN controller for security and monitoring purposes.
