Enable IPv6 unreachable destination messaging
OS10(config)# interface ethernet 1/1/8
OS10(conf-if-eth1/1/8)# ipv6 unreachables
IPv6 hop-by-hop options
A hop-by-hop header extension in an IPv6 packet contains options that are processed by all IPv6 routers in the packet's path.
By default, hop-by-hop header options in an IPv6 packet do not process locally. To enable local processing of IPv6 hop-by-hop
options on an interface, use the ipv6 hop-by-hop command.
Enable IPv6 hop-by-hop options forwarding
OS10(config)# interface ethernet 1/1/8
OS10(conf-if-eth1/1/8)# ipv6 hop-by-hop

network vn-id | all]
Parameters
● vrf vrf-name — (Optional) Enter vrf then the name of the VRF to clear the neighbor
corresponding to that VRF. If you do not specify this option, the neighbors in the default VRF clear.
