Directly Connected Static Route

Directly Connected Static Routes: -
·         A directly connected route that is directly attached to one of the router interfaces. When a router interface is configured with an IP address, the interface becomes a Directly Connected.
·         You must specify only the interface on which all packets are sent to the destination network in a directly connected static route.
·         The router assumes the destination is directly attached to the output interface and the packet destination is used as the next-hop address.
·         Directly Connect static route have a default administrative distance of 0.
·         The next-hop can be an interface, only for point-to-point interfaces.

·         For broadcast interfaces, the next hop must be an IPv4/IPv6 address.

R1#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route
