two vrrp questions


hi group,
I was wondering the following, and hope someone can clarify it a bit more for me. :)
1.) VRRP uses multicast group 224.0.0.18 and has a mac-address of 00:00:5e:00:01: (I/G bit to zero, so a unicast mac-address). What i know is that when converting a multicast ip to a mac-address you should map it the following way: and add: 01:00:5e, why hasnt this been done with VRRP? 2.) VRRP uses 224.0.0.18 which is a link local group, why does it send the packets with a TTL of 255 if this range isnt supposed to be routed anyway?
Thanks, Wouter
