If you have configured the Layer 3 VPN to handle both IPv4 and IPv6 routes, configure
the interface to handle both IPv4 and IPv6 routes by including the

You can configure an EBGP or IBGP multihop session between the PE and CE routers of
a Layer 3 VPN. This allows you to have one or more routers between the PE and CE
routers. Using IBGP between PE and CE routers does not require the configuration of any
additional statements. However, using EBGP between the PE and CE routers requires
the configuration of the multihop
To configure an external BGP multihop session for the connection between the PE and
CE routers, include the

loops, you have to configure a time-to-live (TTL) value for the multihop session:
