a.) only link state routing protocols have this intelligence.

b.) poison reverse.

c.) triggered updates.

d.) garrison-4.

b.) ip address 12.23.4.5 /24 c.) ip address 12.23.4.5 255.255.255.0 d.) ip address 12.23.4.5 mask 255.255.255.0 e.) ip address 12.23.4.5 mask ff:ff:ff:0

c you can change the way the mask is displayed (bitcount, decimal, hex) but you must enter the subnet mask in dotted decimal. router(config-if)#ip address 12.23.4.5 ? a.b.c.d ip subnet mask
