IPv6 configuring multiple address

SuperOmnia
Level 1
Level 1

Hi, I'd like to know if is possible to configure  2 link-local address to the same interface

I want to configure

2001:AAAA::/64 EUI-64(this will generate a link-local address)

but next I want configure

2001:EEEE::1/64

and another link-local but in this case an static one

FE80:DDDD::1/64

(these are not the exact prefixes I'm using, this is just to give the ex)

When I try  : show ipv6 interface brief the only link-local i get is FE80:DDD::1

I want to have the two global each one with his link-local, is it possible?

Hi there,

An IPv6 enabled interface can only have one link-local address per interface, this is automatically created when IPv6 is enabled on the interface (either using 'ipv6 enable' or 'ipv6 address xxxx::/xx'), or when explicitly defined.

The following configuration would be valid:

!
int eth0/1
ipv6 address 2001:aaaa::/64 EUI-64
ipv6 address 2001:eeee::1/64
ipv6 address fe80:dddd::1 link-local
!

cheers,

Seb.

thanks a lot, I was not very sure about it but thanks to you for taking your time to answer me, I appreciate it :D now I can continue doing my practice
