In this example I've got three Cisco IOW v routers that have just booted up.
One is going to act as our client.
One's going to act as a DHB Version 6 a relay agent and one's going to act as our DHB Version 6 server
so let's start with a relay agent.
I'll call this road a relay and then on gigabit 0 0 on the to the interface and actually before configure
IP version 6 addresses let's configure IP version 6 uni cost routing and now on gigabit 00 I'll configure
an IP version 6 address of 2001 face colon colon 1 and then on gigabit 0 1 shut the interface might
be v 6 address 2001 colon One two three four colon colon one slash 64 so show IP interface brief will
show us no IP addresses because no IP version 4 is configured on this rather show IP vs 6 interface
brief however shows us the IP version 6 global unique cost address on gigabit 0 00 as well as the address
on gigabit 0 1 so show IP v 6 interface gigabit 0 0 there is the link local address global unique concert
address and subnet address on gigabit December 1 we've got something similar link local address and
global unique cost address.
Now one thing we need to configure on the relay agent is on the interface that's going to receive the
DHB request we need to configure IP 6 DHEA P relay and point it to the DHB server which in this case
is going to have an IP address of 2001 1 2 3 4 colon colon to so to configured the relay agent we configure
an IP address on gigabit to 0 0 and we configure the relay destination.
So that's the configuration of the relay agent I'm going to enable IP v 6 DCP debugging so that we can
see DHB messages received from the client.
