Connecting IPv6 Isl ands with IPv4 MPLS

Juniper，Junos　6PE－LAB。

Many service providers are looking for ways to provide new revenue-generating services

to their customers. One such service is Internet Protocol version 6 (IPv6). Some enterprise

customers are beginning to experiment with this new version of IP , but are reluctant to

deploy it broadly. Interconnecting multiple sites that use IPv6 can be challenging. Also,

most service providers would prefer to carry this traffic without making major

modifications to their core network.
