+
+Using iproute2 for VRFs
+=======================
+VRF devices do *not* have to start with 'vrf-'. That is a convention used here
+for emphasis of the device type, similar to use of 'br' in bridge names.
+
+1. Create a VRF
+
+ To instantiate a VRF device and associate it with a table:
+ $ ip link add dev NAME type vrf table ID
+
+ Remember to add the ip rules as well:
+ $ ip ru add oif NAME table 10
+ $ ip ru add iif NAME table 10
+ $ ip -6 ru add oif NAME table 10
+ $ ip -6 ru add iif NAME table 10
+
+ Without the rules route lookups are not directed to the table.
+
+ For example:
+ $ ip link add dev vrf-blue type vrf table 10
+ $ ip ru add pref 200 oif vrf-blue table 10
+ $ ip ru add pref 200 iif vrf-blue table 10
+ $ ip -6 ru add pref 200 oif vrf-blue table 10
+ $ ip -6 ru add pref 200 iif vrf-blue table 10
+
+
+2. List VRFs
+
+ To list VRFs that have been created:
+ $ ip [-d] link show type vrf
+ NOTE: The -d option is needed to show the table id
+
+ For example:
+ $ ip -d link show type vrf
+ 11: vrf-mgmt: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+ link/ether 72:b3:ba:91:e2:24 brd ff:ff:ff:ff:ff:ff promiscuity 0
+ vrf table 1 addrgenmode eui64
+ 12: vrf-red: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+ link/ether b6:6f:6e:f6:da:73 brd ff:ff:ff:ff:ff:ff promiscuity 0
+ vrf table 10 addrgenmode eui64
+ 13: vrf-blue: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+ link/ether 36:62:e8:7d:bb:8c brd ff:ff:ff:ff:ff:ff promiscuity 0
+ vrf table 66 addrgenmode eui64
+ 14: vrf-green: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+ link/ether e6:28:b8:63:70:bb brd ff:ff:ff:ff:ff:ff promiscuity 0
+ vrf table 81 addrgenmode eui64
+
+
+ Or in brief output:
+
+ $ ip -br link show type vrf
+ vrf-mgmt UP 72:b3:ba:91:e2:24 <NOARP,MASTER,UP,LOWER_UP>
+ vrf-red UP b6:6f:6e:f6:da:73 <NOARP,MASTER,UP,LOWER_UP>
+ vrf-blue UP 36:62:e8:7d:bb:8c <NOARP,MASTER,UP,LOWER_UP>
+ vrf-green UP e6:28:b8:63:70:bb <NOARP,MASTER,UP,LOWER_UP>
+
+
+3. Assign a Network Interface to a VRF
+
+ Network interfaces are assigned to a VRF by enslaving the netdevice to a
+ VRF device:
+ $ ip link set dev NAME master VRF-NAME
+
+ On enslavement connected and local routes are automatically moved to the
+ table associated with the VRF device.
+
+ For example:
+ $ ip link set dev eth0 master vrf-mgmt
+
+
+4. Show Devices Assigned to a VRF
+
+ To show devices that have been assigned to a specific VRF add the master
+ option to the ip command:
+ $ ip link show master VRF-NAME
+
+ For example:
+ $ ip link show master vrf-red
+ 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP mode DEFAULT group default qlen 1000
+ link/ether 02:00:00:00:02:02 brd ff:ff:ff:ff:ff:ff
+ 4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP mode DEFAULT group default qlen 1000
+ link/ether 02:00:00:00:02:03 brd ff:ff:ff:ff:ff:ff
+ 7: eth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop master vrf-red state DOWN mode DEFAULT group default qlen 1000
+ link/ether 02:00:00:00:02:06 brd ff:ff:ff:ff:ff:ff
+
+
+ Or using the brief output:
+ $ ip -br link show master vrf-red
+ eth1 UP 02:00:00:00:02:02 <BROADCAST,MULTICAST,UP,LOWER_UP>
+ eth2 UP 02:00:00:00:02:03 <BROADCAST,MULTICAST,UP,LOWER_UP>
+ eth5 DOWN 02:00:00:00:02:06 <BROADCAST,MULTICAST>
+
+
+5. Show Neighbor Entries for a VRF
+
+ To list neighbor entries associated with devices enslaved to a VRF device
+ add the master option to the ip command:
+ $ ip [-6] neigh show master VRF-NAME
+
+ For example:
+ $ ip neigh show master vrf-red
+ 10.2.1.254 dev eth1 lladdr a6:d9:c7:4f:06:23 REACHABLE
+ 10.2.2.254 dev eth2 lladdr 5e:54:01:6a:ee:80 REACHABLE
+
+ $ ip -6 neigh show master vrf-red
+ 2002:1::64 dev eth1 lladdr a6:d9:c7:4f:06:23 REACHABLE
+
+
+6. Show Addresses for a VRF
+
+ To show addresses for interfaces associated with a VRF add the master
+ option to the ip command:
+ $ ip addr show master VRF-NAME
+
+ For example:
+ $ ip addr show master vrf-red
+ 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP group default qlen 1000
+ link/ether 02:00:00:00:02:02 brd ff:ff:ff:ff:ff:ff
+ inet 10.2.1.2/24 brd 10.2.1.255 scope global eth1
+ valid_lft forever preferred_lft forever
+ inet6 2002:1::2/120 scope global
+ valid_lft forever preferred_lft forever
+ inet6 fe80::ff:fe00:202/64 scope link
+ valid_lft forever preferred_lft forever
+ 4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP group default qlen 1000
+ link/ether 02:00:00:00:02:03 brd ff:ff:ff:ff:ff:ff
+ inet 10.2.2.2/24 brd 10.2.2.255 scope global eth2
+ valid_lft forever preferred_lft forever
+ inet6 2002:2::2/120 scope global
+ valid_lft forever preferred_lft forever
+ inet6 fe80::ff:fe00:203/64 scope link
+ valid_lft forever preferred_lft forever
+ 7: eth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop master vrf-red state DOWN group default qlen 1000
+ link/ether 02:00:00:00:02:06 brd ff:ff:ff:ff:ff:ff
+
+ Or in brief format:
+ $ ip -br addr show master vrf-red
+ eth1 UP 10.2.1.2/24 2002:1::2/120 fe80::ff:fe00:202/64
+ eth2 UP 10.2.2.2/24 2002:2::2/120 fe80::ff:fe00:203/64
+ eth5 DOWN
+
+
+7. Show Routes for a VRF
+
+ To show routes for a VRF use the ip command to display the table associated
+ with the VRF device:
+ $ ip [-6] route show table ID
+
+ For example:
+ $ ip route show table vrf-red
+ prohibit default
+ broadcast 10.2.1.0 dev eth1 proto kernel scope link src 10.2.1.2
+ 10.2.1.0/24 dev eth1 proto kernel scope link src 10.2.1.2
+ local 10.2.1.2 dev eth1 proto kernel scope host src 10.2.1.2
+ broadcast 10.2.1.255 dev eth1 proto kernel scope link src 10.2.1.2
+ broadcast 10.2.2.0 dev eth2 proto kernel scope link src 10.2.2.2
+ 10.2.2.0/24 dev eth2 proto kernel scope link src 10.2.2.2
+ local 10.2.2.2 dev eth2 proto kernel scope host src 10.2.2.2
+ broadcast 10.2.2.255 dev eth2 proto kernel scope link src 10.2.2.2
+
+ $ ip -6 route show table vrf-red
+ local 2002:1:: dev lo proto none metric 0 pref medium
+ local 2002:1::2 dev lo proto none metric 0 pref medium
+ 2002:1::/120 dev eth1 proto kernel metric 256 pref medium
+ local 2002:2:: dev lo proto none metric 0 pref medium
+ local 2002:2::2 dev lo proto none metric 0 pref medium
+ 2002:2::/120 dev eth2 proto kernel metric 256 pref medium
+ local fe80:: dev lo proto none metric 0 pref medium
+ local fe80:: dev lo proto none metric 0 pref medium
+ local fe80::ff:fe00:202 dev lo proto none metric 0 pref medium
+ local fe80::ff:fe00:203 dev lo proto none metric 0 pref medium
+ fe80::/64 dev eth1 proto kernel metric 256 pref medium
+ fe80::/64 dev eth2 proto kernel metric 256 pref medium
+ ff00::/8 dev vrf-red metric 256 pref medium
+ ff00::/8 dev eth1 metric 256 pref medium
+ ff00::/8 dev eth2 metric 256 pref medium
+
+
+8. Route Lookup for a VRF
+
+ A test route lookup can be done for a VRF by adding the oif option to ip:
+ $ ip [-6] route get oif VRF-NAME ADDRESS
+
+ For example:
+ $ ip route get 10.2.1.40 oif vrf-red
+ 10.2.1.40 dev eth1 table vrf-red src 10.2.1.2
+ cache
+
+ $ ip -6 route get 2002:1::32 oif vrf-red
+ 2002:1::32 from :: dev eth1 table vrf-red proto kernel src 2002:1::2 metric 256 pref medium
+
+
+9. Removing Network Interface from a VRF
+
+ Network interfaces are removed from a VRF by breaking the enslavement to
+ the VRF device:
+ $ ip link set dev NAME nomaster
+
+ Connected routes are moved back to the default table and local entries are
+ moved to the local table.
+
+ For example:
+ $ ip link set dev eth0 nomaster
+

+* Capabilities
+* Provides up to 256 aggregative message per type
+* Provides 4 message types in dword
+* Message type pointers to byte offset
+* Backward Compatibility by using sizeof for the counters.
+* No lock requires for 32bit messages
+* Limitations:
+* In case of messages greater than 32bit, a dedicated mechanism(e.g lock)

+ The driver is known to work with a number of RTL8723AU,
+ RL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU devices
+
+ This driver is under development and has a limited feature
+ set. In particular it does not yet support 40MHz channels
+ and power management. However it should have a smaller
+ memory footprint than the vendor drivers and benetifs
+ from the in kernel mac80211 stack.
+
+ It can coexist with drivers from drivers/staging/rtl8723au,
+ drivers/staging/rtl8192u, and drivers/net/wireless/rtlwifi,
+ but you will need to control which module you wish to load.
+
+ To compile this driver as a module, choose M here: the module will
+ be called r8xxxu. If unsure, say N.
