And when I tried to create a SA, I always got an error for that. Detailed configs look like this: Interface details: vpp# show int Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count VirtualFunctionEthernet0/5/0 1 up 9000/0/0/0 VirtualFunctionEthernet0/6/0 2 up 9000/0/0/0 local0 0 down 0/0/0/0 IPSec configs: set interface state VirtualFunctionEthernet0/5/0 up set interface state VirtualFunctionEthernet0/6/0 up set interface ip address VirtualFunctionEthernet0/5/0 192.168.70.100/24 set interface ip address VirtualFunctionEthernet0/6/0 192.168.100.3/24 set int promiscuous on VirtualFunctionEthernet0/5/0 set int promiscuous on VirtualFunctionEthernet0/6/0 set ip arp VirtualFunctionEthernet0/6/0 192.168.100.4 fa:16:3e:b3:8b:fd set ip arp VirtualFunctionEthernet0/5/0 192.168.70.200 fa:16:3e:f5:2f:e9 ip route add count 1 104.0.0.0/32 via 192.168.100.4 VirtualFunctionEthernet0/6/0 ip route add count 1 004.0.0.0/32 via 192.168.70.200 VirtualFunctionEthernet0/5/0 ipsec spd add 1 set interface ipsec spd VirtualFunctionEthernet0/6/0 1 ipsec sa add 1 spi 1001 esp tunnel-src 192.168.100.3 tunnel-dst 192.168.100.4 crypto-key 2b7e151628aed2a6abf7158809cf4f3d crypto-alg aes-cbc-128 integ-key 6867666568676665686766656867666568676669 integ-alg sha1-96 //This line will return an error ‘ipsec sa: failed’ ipsec sa add 2 spi 25500128 esp tunnel-src 192.168.100.4 tunnel-dst 192.168.100.3 crypto-key 2b7e151628aed2a6abf7158809cf4f3d crypto-alg aes-cbc-128 integ-key 6867666568676665686766656867666568676669 integ-alg sha1-96 ipsec policy add spd 1 outbound priority 100 action protect sa 1 remote-ip-range 104.0.0.0-104.0.0.0 ipsec policy add spd 1 outbound priority 90 protocol 50 action bypass ipsec policy add spd 1 inbound priority 100 action protect sa 1 remote-ip-range 004.0.0.0-004.0.0.0 ipsec policy add spd 1 inbound priority 90 protocol 50 action bypass Anyone know the cause for that?
