Purpose
Specifies a recursive next-hop IP address.
Note The recursive next-hop can be a subnet that is not
directly connected.
The set ip next-hop recursive command does not ensure that
packets are routed through the recursive-next-hop if there is
an intermediate node with a shorter route to the destination
such that the route does not pass through the
recursive-next-hop.
Specifies the output interface from which the packet will be
sent. This action specifies that the packet is forwarded out of
the local interface. The interface must be a Layer 3 interface
(not a switchport).
Packets are forwarded on the specified interface only if one of
the following conditions is met:
• The destination IP address in the packet lies within the IP
subnet to which the specified interface belongs.
• The destination IP address in the packet is reachable
through the specified interface (as per the IP routing
table).
If the destination IP address on the packet does not meet
either of these conditions, the packet is dropped. This action
forces matching packets to be switched in software.k
Sets next hop to which to route the packet if there is no
explicit route for the destination IP address in the packet.
Before forwarding the packet to the next hop, the switch looks
up the packet's destination address in the unicast routing
table. If a match is found, the packet is forwarded by way of
the routing table. If no match is found, the packet is forwarded
to the specified next hop.
