6PE limitations

6PE has the following limitations:

6PE supports only IPv6 unicast forwarding

6PE is supported only in the default VRF

6PE does not support GREv6 over v4 tunnel

NOTE

Do not forward packets from one type of tunnel to another type of tunnel in XPP. Packets may not be
routed properly.

Configuring 6PE

The user must first configure BGP and MPLS to enable 6PE route propagation. To configure 6PE,
the user must enable IPv6 unicast capability and IPv6 label capability for the IPv4 peers. Enter the
following commands under the router bgp level to configure 6PE.

Brocade(config)# router bgp

Brocade(config-bgp)# address-family ipv6 unicast
