ipv6 route ::/0 Null0 200 - applied, no traffic possible

Hi NG,

i'm using a Cisco 3750G Stack with c3750-ipservices-mz.122-53.SE1.bin. Thereby having SDM Prefer set to "desktop IPv4 and IPv6 default" on each

3750.

on the other side having two other 3750, playing HSRPv6 together.

Config 3750 Stack:

interface Vlan4 ipv6 address FE80:620:300::222 link-local ipv6 enable ipv6 ospf 60000 area 0

3750-1:

interface Vlan4 ipv6 address FE80:620:300::213 link-local ipv6 enable ipv6 ospf 200 area 0 standby 51 ipv6 FE80:620:300::214 standby 51 priority 200 standby 51 preempt delay minimum 30 standby 51 track 2 decrement 100

3750-2: interface Vlan4 ipv6 address FE80:620:300::212 link-local ipv6 enable ipv6 ospf 200 area 0 standby version 2 standby 51 ipv6 FE80:620:300::214 standby 51 priority 110 standby 51 preempt delay minimum 30 standby 51 track 2 decrement 100

now on the 3750 Stack we had following command set:

ð ipv6 route ::/0 Null0 100

with this command applied, it was NOT possible to even ping the link-local addresses off either 3750-1 or -2 from the 3750-Stack. As soon as i removed it via no ipv6 route ::/0 Null0 100 it was possible again. Are there known issues with the implementation of IPv6 on Cisco 3750's ?

Thank you

Colin
