E.7. Norms

For our discussion we use the following naming conventions for our variables:
x, and its subscripted variants range over the VRRP routers
p, and its subscripted variants range over the packets or frames
a, and its subscripted variants range over the addresses (IP, MAC).
| handle( x, p) | handling of the packet p by x |
| vset(v) | virtual IP address set of a virtual router v |
| xset(v) | VRRP routers associated with v |
| vmac( v ) | virtual MAC address of a virtual router v |
| Sent(p,a) | p is sent to a |
| ARP(p,a) | p is an ARP request ... |
