Cisco ASR 9000 Series Routing Configuration Guide

A1 and Router C2 to Router A1, native UCMP is preferred. As a result, local UCMP is used only on single
hop destinations, and native UCMP is used for multi-hop destinations.
Figure 23: Unequal Cost Multipath for Static Routing
To configure UCMP for static routing, use the following steps:
1
Enter the global configuration mode.
RP/0/0/CPU0:Router# configure
2
Enter the static routing mode.
RP/0/0/CPU0:Router(config)# router static
3
Configure UCMP with load metric for IPv4 or IPv6 address family.
RP/0/0/CPU0:Router(config-static)# address-family ipv4 unicast
RP/0/0/CPU0:Router(config-static-afi)# 10.10.10.1/32 GigabitEthernet 0/0/0/1 metric 10
In this example, we have configured UCMP for IPv4 address family. To configure UCMP for IPv6 address
family, use the following sample configuration.
RP/0/0/CPU0:Router(config-static)# address-family ipv6 unicast
RP/0/0/CPU0:Router(config-static-afi)# 10:10::1/64 GigabitEthernet 0/0/0/1 metric 10
4
Exit the static configuration mode and commit your configuration.
RP/0/0/CPU0:Router(config-static-afi)# exit
RP/0/0/CPU0:Router(config-static)# exit
RP/0/0/CPU0:Router(config)# commit

Route for 10.10.10.1 is configured via ethernet interface
Repeat this procedure on all routers that need to be configured with UCMP.
