Refer to the exhibit:
Router 1 was experiencing a DDoS attack that was traced to interface gjgabitethernet0/1.
Which statement about this configuration is true?
Refer to the exihibit.
Refer to the exhibit. Routers R1 through R5 are being deployed within the core of a service provider running BGP The core supports distribution of VPNv4 routes using MPLS. R3 currently has multiple paths to reach R4. A network engineer must implement BGP attributes so that R3 can reach R4 via R1. Which action must the engineer take to meet the requirement?
To direct traffic from R3 to R4 via R1, the weight attribute on R3 can be set higher for the route through R1 compared to other routes. Weight is a Cisco-specific BGP attribute that determines the preferred path when multiple routes to the same destination exist. It is local to the router on which it is configured and not advertised to other BGP peers.

Refer to the exihibit.
Refer to the exhibit. The operations team is implementing an LDP-based configuration in the service provider core network with these requirements:
R1 must establish LDP peering with the loopback IP address as its Router-ID.
Session protection must be enabled on R2.
How must the team update the network configuration to successfully enable LDP peering between R1 and R2?
