What defines a host route on a Cisco router?
- An IPv4 static host route configuration uses a destination IP address of a specific device and a /32 subnet mask.
- A static IPv6 host route must include the interface type and the interface number of the next hop router.
- A host route is designated with a C in the routing table.
- The link-local address is added automatically to the routing table as an IPv6 host route.
Explanation: A host route is an IPv4 address with a 32-bit mask, or an IPv6 address with a 128-bit mask. When an active interface on a router is configured with an IPv4 or IPv6 address, a local host route is automatically added to the routing table. A host route is marked with L in the output of the routing table. For IPv6 static routes, the next-hop address can be the link-local address of the adjacent router. In this case you must specify the interface type and the interface number of the local router.
