## Known discrepancies with `aggregate6`
|
|
|
|
|
|
|
|
|
|
* `rs-aggregate` accepts subnet and wilcard mask formats in addition to CIDR, ie all these are valid and equivalent:
|
|
|
|
|
* `1.1.1.0/255.255.255.0`
|
|
|
|
|
* `1.1.1.0/0.0.0.255`
|
|
|
|
|
* `1.1.1.0/24`
|
|
|
|
|
* `-m/--max-prefixlen` supports different maximums for each address family as ipv4,ipv6 format
