Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 69)

The show run command displays the entire name of the static IP route. The show ip static route
command displays an asterisk (*) after the first twelve characters if the assigned name is thirteen
characters or more. The show ipv6 static route command displays an asterisk after the first two
characters if the assigned name is three characters or more.
When displayed in show run , a static route name with a space in the name will appear within quotation
marks (for example, "brcd route").
Changing the name of a static IP route
To change the name of a static IP route, enter the static route as configured. Proceed to enter the new
name instead of the previous name. See the example below.
Static IP route with the original name "abc":
device(config)# ip route 10.22.22.22 255.255.255.255 10.1.1.1 name abc
Change the name of "abc" to "xyz":
device(config)# ip route 10.22.22.22 255.255.255.255 10.1.1.1 name xyz
In this example, "xyz" is the set as the new name of the static IP route.
Deleting the name of a static IP route
To delete the name of a static IP route, use the no command. See the example below.
Static IP route with the name "xyz":
device(config)# ip route 10.22.22.22 255.255.255.255 10.1.1.1 name xyz
To remove the name "xyz" from the static IP route, specify both "name" and the string, in this case
"xyz".
device(config)#no ip route 10.22.22.22 255.255.255.255 10.1.1.1 name xyz
The static route no longer has a name assigned to it.
Configuring load balancing and redundancy using multiple static routes to the same
destination
You can configure multiple static IP routes to the same destination, for the following benefits:
• IP load sharing - If you configure more than one static route to the same destination, and the routes
have different next-hop gateways but have the same metrics, the Layer 3 switch load balances
among the routes using basic round-robin. For example, if you configure two static routes with the
same metrics but to different gateways, the Layer 3 switch alternates between the two routes.
• Backup Routes - If you configure multiple static IP routes to the same destination, but give the
routes different next-hop gateways and different metrics, the Layer 3 switch will always use the route
with the lowest metric. If this route becomes unavailable, the Layer 3 switch will fail over to the static
route with the next-lowest metric, and so on.
NOTE
You also can bias the Layer 3 switch to select one of the routes by configuring them with different
administrative distances. However, make sure you do not give a static route a higher administrative
