[afnog] default gw on Cisco 2960S ...?

[Frank Habicht]

Hi all,

I got a Cisco 2960S L2 switch.
WS-C2960S-48TS-S, (C2960S-UNIVERSALK9-M), Version 15.0(2)SE2
With ipv6 address on vlan 1 and actually logged into it using v6.
from the same vlan.

I want to get the equivalent of "ip default-gateway 10.0.0.1" for v6 so i
can reach it (and it can respond) from elsewhere.

http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/15.0_2_se/configuration/guide/swipv6.html#wp1305314
says to
"sdm prefer dual-ipv4-and-ipv6 default"

but:
SW2#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
SW2(config)#sd?
% Unrecognized command
SW2(config)#sd


:-(

is there any solution?


Thanks,
Frank

PS: it has a "ipv6 nd raguard" command :-)
