You can also configure IP to support equal-cost multipath (ECMP) routes for

traffic distribution. If IP considers the ECMP routes to be the best routes, IP uses

them all in the way you specify — in round-robin fashion, for example — to

forward data. For information, see “Configuring Equal-Cost Multipath Support

for RIP and OSPF” on page 3-16. With ECMP enabled globally on the router, you

can configure up to 12 ECMP static routes.

Using the BCC

To define a static route, go to the global IP prompt (for example,

box; ip

) and

enter:

static-route address

mask

<ip_mask>

next-hop-address

<next_hop>

Table 3-5 describes the required static route parameters.

For example, the following command configures a static route to destination

3.2.4.5/255.255.0.0:

ip#

static-route address 3.2.4.5 mask 255.255.0.0 next-hop-address 2.2.2.4

static-route/3.2.4.5/255.255.0.0/2.2.2.4#

Note:

When you dynamically create a new static route (for example,

128.10.8.0/255.255.255.0/1), the router may generate the following error

message in the router log file:

# 2: 04/16/99 09:44:24.096 WARNING SLOT 5 IP Code: 56

Error when configuring static route 128.10.8.0/255.255.255.0/1

This message indicates that the static route is not configured at the time stated

because all necessary MIB sets are not completed. Error checking occurs as

each attribute is set. The router code generates the error messages to prevent

misconfigured static routes. You can verify that a static route has been created

correctly by issuing a

get

command for the valid attribute in the

wfIpStaticRouteEntry.10.* instance.
