Refer to the exhibit. A route health injector is deployed on the network to monitor reachable services. The route health injector injects /32 prefixes into BGP with the next hop of 98.18.0.2. These /3

AS-path prepending modifies the BGP AS-path attribute to influence inbound path selection from remote ASes, but has no bearing on whether routes from a local RHI are installed into the RIB.

BGP community attributes are used to tag routes for policy decisions such as filtering or local-preference adjustments, and do not affect the ability to establish a BGP session or install routes from a non-directly-connected peer.

MP-BGP extends BGP to carry additional address families such as IPv6 or MPLS VPN prefixes, but standard IPv4 /32 routes from an RHI do not require multiprotocol extensions to be installed in the RIB.

By default, eBGP sets the IP TTL to 1, meaning it expects peers to be directly connected on the same subnet. If the route health injector at 98.18.0.2 is multiple hops away from router A, the BGP packets are discarded before reaching the peer and no session can form. Configuring eBGP multihop raises the TTL, allowing the eBGP session to be established across multiple hops so that the injected /32 prefixes are accepted and installed into the RIB.
