Example Usage Example of how to add a straight forward static route: vpp# ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0 Example of how to delete a straight forward static route: vpp# ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0 Mainly for route add/del performance testing, one can add or delete multiple routes by adding ‘count N’ to the previous item: vpp# ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0 Add multiple routes for the same destination to create equal-cost multipath: vpp# ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 vpp# ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 For unequal-cost multipath, specify the desired weights. This combination of weights results in 3/4 of the traffic following the second path, 1/4 following the first path: vpp# ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 weight 1 vpp# ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 weight 3 To add a route to a particular FIB table (VRF), use: vpp# ip route add 172.16.24.0/24 table 7 via GigabitEthernet2/0/0
