ipv6 and ipv4 router example and ipv6 config errors

[deshmukhrajvardhan]

Hi,

I have been working on a element that handles both ipv4 and ipv6.
It have it working fine with ipv4 but the click config for ipv6 gives errors.
I would appreciate an example click config file for it.

I have looked at the following examples:
https://github.com/kohler/click/blob/6fa978f0188bd0b8a266f65cd0e79d81838b7963/conf/ip601.click
https://github.com/kohler/click/blob/6fa978f0188bd0b8a266f65cd0e79d81838b7963/conf/ip64-nat4.click

Errors:

conf/mfw-ipv6-quic-vm.click:77: While configuring ‘CheckIP6Header@34 :: CheckIP6Header’:
  BADADDRS: parse error
conf/mfw-ipv6-quic-vm.click:79: While configuring ‘rtip6 :: LookupIP6Route’:
  argument 1 should be DADDR/MASK [GW] OUTPUT
  argument 2 should be DADDR/MASK [GW] OUTPUT
conf/mfw-ipv6-quic-vm.click:84: While configuring ‘nda :: IP6NDAdvertiser’:
  argument 1 should be `IP6/MASK ETHADDR'
  argument 1 had no IP6 address and masks
conf/mfw-ipv6-quic-vm.click:95: While configuring ‘c3 :: Classifier’:
  pattern 1: expected a digit
  pattern 2: expected a digit
Router could not be initialized!

Specifications:

Want to route all ipv6 traffic to interface with
ipv6 address: fe80::29e7:d96d:843a:f07
mac address: 00:50:56:A2:7C:42
routes:
