eBGP+ peership between two switches with IPv6 Tunneling

The following figure shows a sample network that contains eBGP+ peers using IPv6 tunneling.

eBGP+ peers with IPv6 tunneling

The configuration in the figure, eBGP+ peers with IPv6 tunneling , assumes that the BGP peer IP address is the next hop.

When you configure the static route for the BGP+ tunnel, you must designate the BGP peer IP address as the next hop in most cases.

You can configure multiple static routes, using the same tunnel, but you must ensure reachability when you create the static routes.
