vpp + frrouting

在frr中查看vrf

给host-ns1_tap配个ip

DBGvpp# set interface ip address host-ns1_tap 192.168.1.230/24
set interface ip address: failed to add 192.168.1.230/24 on host-ns1_tap which conflicts with 192.168.1.229/24 for interface UnknownEthernet5/0/0

报错了先给vpp添加个vrf,再把host-ns1_tap 添加进vrf和给host-ns1_tap 配置ip


DBGvpp# ip table add 100                                      
DBGvpp# set interface ip table host-ns1_tap 100
DBGvpp# set interface ip address host-ns1_tap 192.168.1.230/24
DBGvpp#

DBGvpp# show int addr

show ip route vrf ns1还是什么都没有

ip netns exec ns1 ip a add 192.168.1.231/24 dev veth0 配个ip

host上路由

[root@localhost bin]# ip r show
