Layer 3 Routing Commands 1556
Virtual Router Configuration mode is only available on the N3000/N4000
switches.
Example
console(config-if-vlan10)#ip redirects
ip route
Use the ip route command in Global Configuration mode to configure a
static route. Use the no form of the command to delete the static route.
Syntax
ip route [vrf vrf-name ] networkaddr { subnetmask | prefix-length } {Null 0 |
nexthopip | vlan vlan-id [nexthopip] [ preference ] [name text ]
no ip route [vrf
vrf-name ] networkaddr { subnetmask | prefix-length } {Null 0
|
nexthopip | vlan vlan-id [nexthopip]}
• vrf-name —The name of the VRF if which the route is to be installed. If no
vrf is specified, the route is created in the global routing table.
•
networkaddr — IP address of destination interface.
•
subnetmask —A 32 bit dotted-quad subnet mask. Enabled bits in the mask
indicate the corresponding bits of the network address are significant.
Enabled bits in the mask must be contiguous.
•
prefix-length —A forward slash followed by an integrer number ranging
from 1-32 (e.g., /24). The integer number indicates the number of
significant bits in the address beginning with the leftmost (most
significant) bit.
•
nexthopip —The next-hop IPv4 address is specified in the argument
nexthopip. Packets matching the destination route are forwarded to the
next hop IP address.
•
vlan-id —A configured VLAN routing interface identifier. If a VLAN
routing interface is specified, it imports the associated subnet into the
default routing instance from the VRF associated with the VLAN.
•
Null0 —The optional Null0 keyword indicates that packets matching the
route are dropped. This capability allows the administrator to purposefully
implement a black hole for selected traffic.
