From: colin on 6 May 2010 05:26 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: � 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 |
