1、创建删除vrf表
|
1 2 3 4 |
vpp# ip table ? ip table ip table [add|del] <table-id> vpp# ip6 table ? ip6 table ip6 table [add|del] <table-id> |
2、端口绑定及查看端口绑定情况
1）绑定及解绑端口
|
1 2 3 |
ip6 table add 100 //ip6接口VRF表100 //将eth1网卡绑定到vrf100上面 set interface ip6 table eth1 100 //当作主干路由出口,将该端口绑定到主vrf 0 |
重点：ip参数是设置ipv4的vrf，ip6参数是设置ipv6的vrf，两种ip形式分别拥有默认ID为0的vrf，并相互不重叠；需要在端口绑定完VRF之后，再设置IP地址；若要删除某端口绑定vrf，需要提前删除其ip，否则报错IP addresses are still present on XXX;

1 2 3 4 |
vpp# create tap id 9 vpp# set int ip address tap9 10.10.10.1/24 vpp# set int ip address del tap9 10.10.10.1/24 vpp# set int ip table tap9 0 |
2）查看端口绑定vrf情况
|
1 2 3 4 5 6 7 8 |
vpp# set int ip address tap9 10.10.10.1/24 vpp# set int ip address tap10 10.10.1.1/24 vpp# show int addr local0 (dn): tap10 (up): L3 10.10.1.1/24 ip4 table-id 100 fib-idx 1 tap9 (up): L3 10.10.10.1/24 ip4 table-id 100 fib-idx 1 |
以上命令，可以确认，tap9和tap10接口绑定到vrf100上面。
3.显示VRF
显示指定vrf表或所有表

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
