Satya,
Some more info about the router plugin. I just realised that the current
extras/router-plugin
does not build for 20.01 'cos of ip-neighbor/ updates in 20.01.
I'm going to push a short example below using BGP in FRR.

After the following configuration, the traffic over tap interface can be
observed
via `tcpdump- i vpp1`. The neighborhood and route can be seen with the
`show ipv6 ospf6 neighbor/route` command.

+## Configure VPP and FRRouting for BGP
+This document describes how to configure the VPP with hicn_router plugin
and FRR to enable the BGP 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 10.0.10.1/24
+ - enable tap-inject # This creates the taps by router plugin
+ - show tap-inject # This shows the created taps
+
+- Setup the tap interface
+ - ip addr add 10.0.10.1/24 dev vpp0
+ - ip link set dev vpp0 up
+```
+### FRR configuration:
+Assume there are two nodes with 1234,5678 AS numbers. This is the
configuration of node A with AS number 1234
+
+ (1234)A(2001::1) ======
(2001::2)B(5678)
+```
+ - /usr/lib/frr/frrinit.sh start &
+ - vtysh
+ - configure terminal
+ - router bgp 1234
+ - neighbor 2001::2 remote-as 5678
+ - address-family ipv6 unicast
+ - neighbor 2001::2 activate
+ - exit-address-family
+```

This will break 19.08 but will support 20.01 as in our project we only
support the latest stable (there are tags on older releases though).
The BGP example may be useful for your use case. Consider it v
experimental but if you make it
working for your use case please share your findings with working
configurations in hicn-...@lists.fd.io.
The OSPF6 example is in here
https://hicn.readthedocs.io/en/latest/control.html#routing-plugin-for-vpp-and-frrouting-for-ospf6
but it has to be updated with also v4.
