Hi everybody.
How is everyone doing ?
How can i configure my cisco router say R1 to advertises a ipv6- prefix and prefixes?
R2(config) ipv6 unicast-routing
R2(config) int s0/0
R2(config-if) ipv6 address 2000::1/64
Now I want to tell router to advertise ipv6 prefix : 2000::/64, ipv6 prefix 2001::/64 . How could i do that ?
thanks and have a nice weekend.

Hi,
It is supposed to work as follows:
When R1 has a set of ipv6 prefixes, these will be announced by R1 to all hosts on the network.
You can verify this by entering: deb ipv6 neighbor
Unless R2 also has these prefixes, it will not announce them.
R2 can be autoconfigured from R1 when you specify R2's interface as ipv6 address autoconfig

Hi Sarah,
Hope you are doing well.
You can add multiple prefixes to the interface, but only 2000::1/64 is a host address the other 2 are subnets.
interface GigabitEthernet1/0/2
ipv6 address 2000::/64
ipv6 address 2000::1/64
ipv6 address 2001::/64
end
or use static ip
ipv6 route 2000::/64 null 0

Thanks Reza and hope you are doing well as well
I understand how to configure ipv6 address statically on an interface.
My intention is to learn stateless dhcp ipv6;I was reading about stateless dhcpipv6.;my book does not say anything as to how we can implement stateless dhcp ipv6.
I came with my own scenario just to get a basic idea as shown below:
R1------------------------R2
R1 is configured with ipv6 address autoconfig, we want R2 to advertises these prefixes 2000::/64,2001::/64 to R1 via neighbor advertisement messages.
ipv6 address 2000::/64
ipv6 address 2000::1/64
ipv6 address 2001::/64
end
thanks Reza .
