11.2Multipath Commands
The following table lists the multipath commands:
Task | Command |
Enabling HRW method | Blackbox/configure/ip/multicast> multipath |
Enabling Cisco method | Blackbox/configure/ip/multicast> multipath cisco |
Disabling Multipath | Blackbox/configure/ip/multicast> no multipath |
| Blackbox/configure/ip/multicast> no multipath cisco |
Display RPF selection | Blackbox>show ip rpf <addr> |

For equal cost routes the nexthops are stored in the increasing (ascending) order of IP address. show ip rpf command displays the selected path, based on the configured multipath method and the nexthops of the best route to the IP address passed.
