+# 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".
