ip route

Last Updated : Oct 26, 2015 |
Establishes a static route. Use no ip route to remove a static route.
Prolog information

Syntax

ip route ip_addr mask {{next_hop [next_hop [next_hop]] } | {interface_type interface_number}} [cost] [preference] [permanent | {track track-index} | Null0]
Note:
You can specify up to three next hops. However, if you apply tracking, you can specify only one next hop.
If you wish to establish a route through the FastEthernet interface on which DHCP address negotiation is configured, you must specify the interface type as the FastEthernet interface.
When applying tracking to a static route, a PBR next hop, or the DHCP client default route, you must specify the same next hop for the object tracker’s RTR (use the next hop command in rtr context).
Object tracking cannot be configured on Null0 or on a permanent route.

Examples

To create a static route on IP address 132.55.0.0 with subnet mask 255.255.0.0 following the path 132.55.4.45, with cost of 3, priority of high, and object tracker 6:
Gxxx-001(super)# ip route 132.55.0.0 255.255.0.0 132.55.4.45 3 high track 6
To create a static discard route on IP address 134.66.0.0:
Gxxx-001(super)# ip route 134.66.0.0 255.255.0.0 Null0
To create a static route over the WAN Fast Ethernet when running DHCP client:
Gxxx-001# ip route 1.1.1.0 255.255.255.0 FastEthernet
