1. It's just binary. Each octet of an ipv4 address equals two hex nibbles of an ipv6 address. So if you have ipv4 10.10.157.4 as an ipv4 address, then you have a ipv6 site local address with 2nd/3rd octets from IPv4 as the subnet: 10 = 0A in hex 157 = 9D in hex FEC0:0:0:A9D::/64 would be your ipv6 subnet there... 2. Use the same group setup, just set a lower IP address as the RP's announced address. MA's will select based on highest IP address. Check out http://www.cisco.com/warp/public/105/rp_announce.html HTH,

How to calculate the address for IPv6 if its mentioned that the 3rd octet should be the IPv4 octet address. For example: 2001:ABCD:123::/64 is the IPv6 subnet and Ipv4 add is 192.168.31.3. 2. How to make a router back up RP for another RP for the same group the Active RP is serving. Using Auto-RP only no BSR. I think just configure the other back up RP address with the static configuration with the matching group. Any thoughts on this ??? I will keep on borthering you guys !!
