Re: [mpls-linux-general] IPV6 over MPLS

[Vino T. <jv...@te...>]

Hello,

My requirement is to connect to isolated IPV6 network over an existing
IPV4/MPLS network. 

IPV6 Cloud ---- Linux --- MPLS/IPV4 cloud ----- Linux ---- IPV6 Cloud

What is the best way out? What type of translation is suitable for this
scenario (6to4/6over4/6in4 etc)?

Regards,
Vino.
