Configuring /48 Address
« on: July 22, 2011, 07:37:04 AM »

I have /48 address that I am now ready to configure but confuse few things:

1)  Does my tunnel endpoint addresses change from the Route /64 address provided?

2)  I am going to add 3 levels of routers,   the gateway connecting the tunnel, then 2 level of IPv6 only routers.   Does any have a suggestion on how to subnet the /48 addresses:       I am adding an image of proposed network.

3) I will have LAN off each of the routers and looking at implementing routing protocol.   I know HE supports BGP and would like to implement it.   Does anyone have any example of Cisco configuration for BGP.

1) Your tunnel endpoint address will not change, as it is not in either the routed /64 or the routed /48. You have a separate /64 for the tunnel.

3) To set up a BGP tunnel, you will need your own RIR-assigned ASN and PI space.
