[f-nsp] Best practise for dual-stack IPv6 on Jetcore-based devices

[Mischa Peters]

Hi Chris,

What I have been doing for some time now is the following:

Create VLAN
Add router-interface to VLAN
Add ve with IPv4 and IPv6 address.

!
vlan 203 by port
 tagged ethe 1/4 to 1/8 ethe 2/1 
 router-interface ve 203
!

interface ve 203
 ip address xx.xx.xx.xx/24
 ipv6 address xxxx:xxxx:xxxx:xxxx::1/64
 ipv6 enable
 ipv6 nd suppress-ra
 ip vrrp-extended vrid 203
  backup priority 100 track-priority 20
  ip-address xx.xx.xx.xx
  track-port e 1/1
  enable
!

The only unfortunate thing is that VRRP-e doesn't support IPv6.

Regards,

Mischa
