I'm just struggling with a IPv4/IPv6 Dual Stack Setup for our new hosting environment. As central routers/switches I've got two Cisco Catalyst 3750G-48TS. The switches are not stacked, for IPv4 they are identically configured for routing and HSRP for redundancy on the first hop.
For Ipv6 I've tried to use the same configuration with routing and HSRP, but I had to learn that the Cisco switches are only able to do HSRP for IPv4 or IPv6
Now I am trying to find a working setup for IPv6 with the given equipment and I've got a couple questions:
IPv6 does Router advertisements and the network devices are learning these routers. How fast does the network devices mitigate a outage of a router?
Given that the IPv6 RA is distributing the routers, what does HSRP good to a IPv6 network?
