Have you set the correct SDM template ie. what does "sh sdm prefer" show ?

switch#sh sdm prefer

The current template is "aggregate default" template.

The selected template optimizes the resources in

the switch to support this level of features for

8 routed interfaces and 1024 VLANs.

number of unicast mac addresses: 6K

number of IPv4 IGMP groups + multicast routes: 1K

number of IPv4 unicast routes: 12K

number of directly-connected IPv4 hosts: 6K

number of indirect IPv4 routes: 6K

number of IPv4 policy based routing aces: 0

number of IPv4/MAC qos aces: 1.125k

number of IPv4/MAC security aces: 1K

so i have configured:

switch(config)#sdm prefer dual-ipv4-and-ipv6 default

Changes to the running SDM preferences have been stored, but cannot take effect

until the next reload.

Use 'show sdm prefer' to see what SDM preference is currently active.

i have reloaded

sw3750-bb-pop-si#sh sdm prefer

The current template is "aggregate IPv4 and IPv6 default" template.

The selected template optimizes the resources in

the switch to support this level of features for

8 routed interfaces and 1024 VLANs.

number of unicast mac addresses: 2K

number of IPv4 IGMP groups + multicast routes: 1K

number of IPv4 unicast routes: 5K

number of directly-connected IPv4 hosts: 2K

number of indirect IPv4 routes: 3K

number of IPv6 multicast groups: 1.125k

number of directly-connected IPv6 addresses: 2K

number of indirect IPv6 unicast routes: 3K

number of IPv4 policy based routing aces: 0

number of IPv4/MAC qos aces: 1.125k

number of IPv4/MAC security aces: 1K

number of IPv6 policy based routing aces: 0

number of IPv6 qos aces: 0.875k

number of IPv6 security aces: 0.5K

and ...

switch(config)#ipv6 unicast-routing

switch(config)#

command entered succesfully !!

THANK YOU VERY VERY VERY MUCH.

Check your sdm prefere template. To use IPv6 you need the template dual-ipv4-and-ipv6.

Use the command " show sdm prefer" to see what template you are using.

Changes to the applied template requires a reboot to the switch.
