[c-nsp] IPv6: GLBP Address

[Friedemann Stoyan]

Hello Experts,

I'm trying to configure the same link local adddress (fe80::1) as glbp
address at all SVIs, but the switch (Sup2T with 15.1(1)SY1) refuse
this:

#sh run int vl 1
Building configuration...

Current configuration : 100 bytes
!
interface Vlan1
 no ip address
 glbp 0 ipv6 FE80::1
 shutdown
 ipv6 address 2001:DB8:1::1/64
end

#sh run int vl 2
Building configuration...

Current configuration : 79 bytes
!
interface Vlan2
 no ip address
 shutdown
 ipv6 address 2001:DB8:2::1/64
end

#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
(config)#interface Vlan2
(config-if)#glbp 0 ipv6 FE80::1
% Address FE80::1 in group 0 - interface Vlan1
(config-if)#
(config-if)#glbp 2 ipv6 FE80::1
% Address FE80::1 in group 0 - interface Vlan1
(config-if)#

Why? What kind of limitation causes this behavior?
