A prefix is a group of one or more individual IP addresses or IP address
subnets. Prefixes are used with Path Set Policies and Priority Policies. They can be
either global or local in scope.
- Global prefixes are used when traffic of interest across all sites in a network can be identified with the same set of prefixes. For example, facilities infrastructure or print services for an enterprise.
- Local prefixes are used when specific prefix values change by branch location. Use of local prefixes can simplify creation and administration of rules. For example, a subset of IP addresses within a subnet.Prefixes configured under path are only applicable for Path Policy Sets and prefixes configured under QoS are only applicable for QoS Policy Sets.
Configure Local Prefixes
- Select .Alternatively, select QoS and then QOS Prefixes.Click Create Global Prefix.On the Add Path Global Prefix screen, enter a Name and optionally a Description for the prefix.Enter IP Prefixes.IP addresses within a prefix are defined by the subnet. For example, 10.1.1.0/24 defines the entire limit of 255 IP addresses in that subnet.The following IPv6 addressing formats are supported:
- Eight groups of four hexadecimal digits: xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx
- Suppressed leading zeros in each 16-bit field: xxxx:xxx:xx represents xxxx:xxxx::xxxx:xxxx
- Two colons to represent longest sequence of consecutive all-zero fields: xxxx:xxx:xxxx represents xxxx:xxx:xxxxx:x
Add IP Prefix to add more than one IP prefix.Select Path for Create For Policy Types.Click Create.Configure Local Prefixes
- Select .Alternatively, select QoS and then QOS Prefixes.Select Local and click Create Local Prefix.On the Add Path Local Prefix screen, enter a Name and optionally a Description and Tags for searching.Select Path for Create For Policy Types.Click Save.
