[vpp-dev] Service chaining with segment routing along with nsh vxlan tunnel

Suman Kpatra/KOL/TCS <suman.kpatra@...> #92 Dear all, Trying out service chaining with segment routing along with nsh vxlan tunnel for the following use case: Source---->VPP1--->Service1---->VPP1--->VPP2--->Service2--->VPP2--->VPP3--->Service3---VPP3--->Destination Created sr tunnel between Source,VPP1,VPP2,VPP3,Destination Following are the configuration: Source ifconfig eth2 up ip addr add 192.168.50.20 dev eth2 ----------------------------------------------------------------------------------------------------------------------------------------------------------------- VPP1 vppctl set int state GigabitEthernet0/a/0 up vppctl set int ip address GigabitEthernet0/a/0 192.168.50.91/24 vppctl nsh vxlan tunnel src 192.168.50.20 dst 192.168.50.91 c1 9901 c2 9902 c3 9903 c4 9904 spi 1 si 255 vni 16777215 md-type 1 next-ip4 decap-next nsh-vxlan-gpe vppctl nsh vxlan tunnel src 192.168.50.91 dst 192.168.50.71 c1 9901 c2 9902 c3 9903 c4 9904 spi 1 si 255 vni 16777215 md-type 1 next-ip4 decap-next nsh-vxlan-gpe vppctl nsh vxlan tunnel src 192.168.50.71 dst 192.168.50.91 c1 9901 c2 9902 c3 9903 c4 9904 spi 1 si 254 vni 16777215 md-type 1 next-ip4 decap-next nsh-vxlan-gpe vppctl nsh vxlan tunnel src 192.168.50.91 dst 192.168.50.92 c1 9901 c2 9902 c3 9903 c4 9904 spi 1 si 254 vni 16777215 md-type 1 next-ip4 decap-next nsh-vxlan-gpe vppctl sr tunnel src 192.168.50.20 dst 192.168.50.21/24 next 192.168.50.92 next 192.168.50.93 next 192.168.50.21 tag 192.168.50.91 InPE 1 clean ----------------------------------------------------------------------------------------------------------------------------------------------------------------- Service1 ifconfig eth2 up ip addr add 192.168.50.71 dev eth2 ----------------------------------------------------------------------------------------------------------------------------------------------------------------- VPP2 vppctl set int state GigabitEthernet0/a/0 up vppctl set int ip address GigabitEthernet0/a/0 192.168.50.92/24 vppctl nsh vxlan tunnel src 192.168.50.92 dst 192.168.50.72 c1 9901 c2 9902 c3 9903 c4 9904 spi 1 si 254 vni 16777215 md-type 1 next-ip4 decap-next nsh-vxlan-gpe vppctl nsh vxlan tunnel src 192.168.50.72 dst 192.168.50.92 c1 9901 c2 9902 c3 9903 c4 9904 spi 1 si 253 vni 16777215 md-type 1 next-ip4 decap-next nsh-vxlan-gpe vppctl nsh vxlan tunnel src 192.168.50.92 dst 192.168.50.93 c1 9901 c2 9902 c3 9903 c4 9904 spi 1 si 253 vni 16777215 md-type 1 next-ip4 decap-next nsh-vxlan-gpe ----------------------------------------------------------------------------------------------------------------------------------------------------------------- Service2 ifconfig eth2 up ip addr add 192.168.50.72 dev eth2 ----------------------------------------------------------------------------------------------------------------------------------------------------------------- VPP3 vppctl set int state GigabitEthernet0/a/0 up vppctl set int ip address GigabitEthernet0/a/0 192.168.50.93/24 vppctl nsh vxlan tunnel src 192.168.50.93 dst 192.168.50.73 c1 9901 c2 9902 c3 9903 c4 9904 spi 1 si 253 vni 16777215 md-type 1 next-ip4 decap-next nsh-vxlan-gpe vppctl nsh vxlan tunnel src 192.168.50.73 dst 192.168.50.93 c1 9901 c2 9902 c3 9903 c4 9904 spi 1 si 252 vni 16777215 md-type 1 next-ip4 decap-next nsh-vxlan-gpe vppctl nsh vxlan tunnel src 192.168.50.93 dst 192.168.50.21 c1 9901 c2 9902 c3 9903 c4 9904 spi 1 si 252 vni 16777215 md-type 1 next-ip4 decap-next nsh-vxlan-gpe vppctl sr tunnel src 192.168.50.21 dst 192.168.50.20/24 next 192.168.50.92 next 192.168.50.91 next 192.168.50.20 tag 192.168.50.93 InPE 1 clean ----------------------------------------------------------------------------------------------------------------------------------------------------------------- Service3 ifconfig eth2 up ip addr add 192.168.50.73 dev eth2 ----------------------------------------------------------------------------------------------------------------------------------------------------------------- Destination ifconfig eth2 up ip addr add 192.168.50.21 dev eth2 ----------------------------------------------------------------------------------------------------------------------------------------------------------------- Intention: Packets destined for destination from source should flow through the following service1,service2,service3.
