Hi all,

one of Chris Bryant's videos has the following route summarization example:
R2 has loopback21 ( and loopback22 (

and RIP summarizes the two addrs as


But from my understanding, these 2 addrs should be summarized as, since from the binaries:
00010100.00000001.00000001.00000001 (
00010100.00000010.00000001.00000001 (

which one is correct?

Thanks in advance.
