IP Route ========== Summary/Usage -------------- `ip route [add|del] [count <*n*>] <*dst-ip-addr*>/<*width*> [table <*table-id*>] via [next-hop-address] [next-hop-interface] [next-hop-table <*value*>] [weight <*value*>] [preference <*value*>] [udp-encap-id <*value*>] [ip4-lookup-in-table <*value*>] [ip6-lookup-in-table <*value*>] [mpls-lookup-in-table <*value*>] [resolve-via-host] [resolve-via-connected] [rx-ip4 <*interface*>] [out-labels <*value value value*>]` Description ------------ This command is used to add or delete IPv4 or IPv6 routes. All IP Addresses ('<*dst-ip-addr*>/<*width*>', '<*next-hop-ip-addr*>' and '<*adj-hop-ip-addr*>') can be IPv4 or IPv6, but all must be of the same form in a single command. To display the current set of routes, use the commands 'show ip fib' and 'show ip6 fib'. Example Usage -------------- Example of how to add a straight forward static route: .. code-block:: console 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: .. code-block:: console 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: .. code-block:: console 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: .. code-block:: console 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: .. code-block:: console 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: .. code-block:: console vpp# ip route add 172.16.24.0/24 table 7 via GigabitEthernet2/0/0 Declaration and Implementation --------------------------------- **Declaration:** ip_route_command (src/vnet/ip/lookup.c line 641) **Implementation:** vnet_ip_route_cmd Ping ===== Summary/Usage -------------- ping {<*ip-addr*> | ipv4 <*ip4-addr*> | ipv6 <*ip6-addr*>} [ipv4 <*ip4-addr*> | ipv6 <*ip6-addr*>] [source <*interface*>] [size <*pktsize*>] [interval <*sec*>] [repeat <*cnt*>] [table-id <*id*>] [verbose] Description ------------ This command sends an ICMP ECHO_REQUEST to network hosts. The address can be an IPv4 or IPv6 address (or both at the same time). Example Usage -------------- Example of how ping an IPv4 address: .. code-block:: console vpp# ping 172.16.1.2 source GigabitEthernet2/0/0 repeat 2 64 bytes from 172.16.1.2: icmp_seq=1 ttl=64 time=.1090 ms 64 bytes from 172.16.1.2: icmp_seq=2 ttl=64 time=.0914 ms Statistics: 2 sent, 2 received, 0% packet loss Example of how ping both an IPv4 address and IPv6 address at the same time: vpp# ping 172.16.1.2 ipv6 fe80::24a5:f6ff:fe9c:3a36 source GigabitEthernet2/0/0 repeat 2 verbose Adjacency index: 10, sw_if_index: 1 Adj: ip6-discover-neighbor Adj Interface: 0 Forced set interface: 1 Adjacency index: 0, sw_if_index: 4294967295 Adj: ip4-miss Adj Interface: 0 Forced set interface: 1 Source address: 172.16.1.1 64 bytes from 172.16.1.2: icmp_seq=1 ttl=64 time=.1899 ms Adjacency index: 10, sw_if_index: 1 Adj: ip6-discover-neighbor Adj Interface: 0 Forced set interface: 1 Adjacency index: 0, sw_if_index: 4294967295 Adj: ip4-miss Adj Interface: 0 Forced set interface: 1 Source address: 172.16.1.1 64 bytes from 172.16.1.2: icmp_seq=2 ttl=64 time=.0910 ms Statistics: 4 sent, 2 received, 50% packet loss Declaration and Implementation ------------------------------- Declaration: ping_command (src/vnet/ip/ping.c line 899) Implementation: ping_ip_address Set Interface IP Address ========================= `Set Interface IP Address <../interface/setinterface.html#set-interface-ip-address>`_ Show IP Arp ============= `Show IP-Arp <../show/show.html#show-ip-arp>`_ Show IP Fib ============ `Show IP-Fib <../show/show.html#show-ip-fib>`_
