release dhcp fastethernet PORT/PORT
release dhcp serial PORT/PORT
renew dhcp fastethernet PORT/PORT
renew dhcp serial PORT/PORT


added router interface commands:
vrrp [1-255] ip A.B.C.D
vrrp [1-255] preempt
vrrp [1-255] preempt delay minimum [0-3600]
vrrp [1-255] priority [0-255]
no vrrp [1-255] ip A.B.C.D
no vrrp [1-255] preempt
no vrrp [1-255] preempt delay minimum [0-3600]
no vrrp [1-255] priority [0-255]
vrrp [1-255] track [1-500]
no vrrp [1-255]
no vrrp [1-255] track [1-500]
vrrp [1-255] track [1-500] decrement [1-255]
no vrrp [1-255] track [1-500] decrement [1-255]

improved layer 2 & layer3 path finding logic
improved DHCP address assignment speed
improved routing table update routine
improved switchport status checking
added multiple invalid entry checks and messages
added network and broadcast address checks when setting interface ip address
added lab alert for possible ip address conflict

fixed number range checking
leading zeros on type numbers removed
ospf no longer takes 0.0.0.0 as router-id
fixed configuration issue when setting a loopback address with 255.255.255.255 mask
fixed ospf path finding
