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
|
|

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
