Ip Address Notation - Cisco ASR 5000 Administration Manual

IP Address Notation

[source]
To create a context called source using a configuration file, you would use a text editor to create a new file
that consists of the following:
config

For some configuration commands, the CLI also accepts CIDR notation. Always view the online Help for the
CLI command to verify acceptable forms of IP address notation.
