An engineer is configuring a network and needs packets to be forwarded to an interface for any destination address that is not in the routing table.
What should be configured to accomplish this task?
To forward packets to an interface for any destination address that is not in the routing table, the correct configuration is to use the 'set ip default next-hop' command. This command ensures that if a destination IP address does not exist in the routing table, the packet is policy routed to a specified next-hop address, thereby achieving the intended routing behavior for undefined addresses.
- The "set ip default next-hop" command verifies the existence of the destination IP address in the routing table: * If the destination IP address exists in the RT, the command does not policy route the packet, but forwards the packet based on the routing table. * If the destination IP address does not exist in the RT, the command policy routes the packet by sending it to the specified next hop. - The "set ip next-hop" command verifies the existence of the destination IP address in the routing table: * If the next hop exists in the routing table, then the command policy routes the packet to the next hop. * If the next hop does not exist in the routing table, the command uses the routing table to forward the packet.
The given answer is correct
B for sure

B for sure
This command specifies the next-hop address to use if there is no explicit route for the destination in the routing table. This is typically used in PBR to specify a default next-hop for packets that do not match any of the other more specific routes in the routing table.
B is correct
