Hi, I am expanding my networks, so I changed original
172.21.87.64/27 to 172.21.87.64/26, this will give Me two /27 block
and also 172.21.87.128/25 that will give me two biger /26 block.
Now I can configure 1 smaller /27 network, two biger /26 network, and
one /27 divided to eight /30 for peering links. hopefully this
allocation will fit my future usage.
