Hi Guys,
Just an off topic,
On my way to exploring DocCD in the final days, every-time i read 31-Bit
Prefixes in IP Addressing Section i got curious to lab it up and see how
they work, finally i have tested them in 2 min scenario. There is no room
for directed broadcasts as you can see only 2 addresses are there.
R4 IP: 150.1.1.0/31
R5 IP: 150.1.1.1/31
Rack1R4#sh run inter s1/1
Building configuration...
Current configuration : 107 bytes
!
interface Serial1/1
ip address 150.1.1.0 255.255.255.254
serial restart-delay 0
clock rate 64000
end
---------------------------------------
Rack1R5#sh run inter s1/1
Building configuration...
Current configuration : 89 bytes
!
interface Serial1/1
ip address 150.1.1.1 255.255.255.254
serial restart-delay 0
end
---------------------------------------
Rack1R5#ping 150.1.1.0
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 150.1.1.0, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/34/64 ms
