# Configure VPP and FRRouting for OSPF6
This document describes how to configure the VPP with hicn_router plugin and FRR to enable the OSPF protocol. The VPP and FRR
are configured in a docker file.
## DPDK configuration on host machine:
- Install and configure dpdk
- make install T=x86_64-native-linux-gcc && cd x86_64-native-linux-gcc && sudo make install
- modprobe uio
- modprobe uio_pci_generic
- dpdk-devbind --status
- the PCIe number of the desired device can be observed ("xxx")
- sudo dpdk-devbind -b uio_pci_generic "xxx"
## VPP configuration:
- Run and configure the VPP (hICN router plugin is required to be installed in VPP)
- set int state TenGigabitEtherneta/0/0 up
- set int ip address TenGigabitEtherneta/0/0 a001::1/24
- create loopback interface
- set interface state loop0 up
- set interface ip address loop0 b001::1/128
- enable tap-inject # This creates the taps by router plugin
- show tap-inject # This shows the created taps
- ip mroute add ff02::/64 via local Forward # ff02:: is multicast ip address
- ip mroute add ff02::/64 via TenGigabitEtherneta/0/0 Accept
- ip mroute add ff02::/64 via loop0 Accept
- Setup the tap interface
- ip addr add a001::1/24 dev vpp0
- ip addr add b001::1/128 dev vpp1
- ip link set dev vpp0 up
- ip link set dev vpp1 up
## FRR configuration:
- Run and configure FRRouting (ospf)
- /usr/lib/frr/frrinit.sh start &
- vtysh
- configure terminal
- router ospf6
- area 0.0.0.0 range a001::1/24
- area 0.0.0.0 range b001::1/128
- interface vpp0 area 0.0.0.0
- interface vpp1 area 0.0.0.0
- end
- wr
- add "no ipv6 nd suppress-ra" to the first configurtion part of the /etc/frr/frr.conf
After the following configuration, the traffic over tap interface can be observered through "tcpdump- i vpp1".
The neighborhood and route can be seen by the "show ipv6 ospf6 neighbor/route".
