Recursive Route Lookup occurs when the #Router has to perform multiple lookups in the #Routing Table before forwarding the packet.
Recursive Route Lookup

Static Routing
In #Cisco Internetwork Operating System (IOS), this could be done using the command
ip route
and supply it with the destination network address, its subnet mask and the next-hop router’s IP address or the outgoing interface (called exit interface). Since using next-hop router’s IP address for static route could result in Recursive Route Lookup#, it is advised to use exit interface when ever possible. However, in the case of configuring on an Ethernet# link, the best practice is to configure with both the next-hop router’s IP address and the exit interface to avoid Address Resolution Protocol (ARP)# shenanigans.
