How to Add Mappings to VPN-based Subscribers
There are three types of mappings that can be added to an existing VPN-based subscriber:
• A set of IP addresses defined as IP@VPN
• A complete VPN (this is actually a special case of IP@VPN mappings, in which the mapping is
defined as 0.0.0.0/0@VPN)
• All the IP addresses of a CE router, defined by a AS:value@VPN-NAME (BGP community)
How to Add IP Address Mappings
Options
The following options are available
• SUB-NAME — The name of the subscriber to be associated with the specified community attribute
• IP1[/RANGE][,...]@VPN-NAME — IP address or addresses to assign to the VPN
– IP = the IP address. This may be any of the following
– a single IP address (x.x.x.x)
– a single range of IP addresses (x.x.x.x/y)
– a list of IP addresses separated by commas (x.x.x.x, y.y.y.y, z.z.z.z)
– a list of IP address ranges (x.x.x.x/a, y.y.y.y/b, z.z.z.z/c)
– VPN-NAME = name of the VPN to which the community attribute will be assigned
• --additive-mappings — Use this option to add the new mapping(s) to any existing ones. (Without
this option, any existing mappings are overwritten.)
Step 1 From the shell prompt, type the following command: p3subs –-add -–subscriber=SUB-NAME
--ip=IP1[/RANGE][,...]@VPN-NAME [--additive-mappings]
How to Add VPN-based Mappings
This option is supported to provide backwards compatibility with MPLS/VPN-based subscribers in
releases before 3.1.5.
Options
The following options are available
• SUB-NAME — The name of the subscriber to be associated with the specified community attribute
• VPN-NAME — The name of the VPN to which the subscriber will be mapped. (This option is
equivalent to defining the mapping as 0.0.0.0/0@VPN)
• --additive-mappings — Use this option to add the new mapping(s) to any existing ones. (Without
this option, any existing mappings are overwritten.)
Step 1 From the shell prompt, type the following command: p3subs –-add -–subscriber=SUB-NAME
–-vpn=VPN-NAME [--additive-mappings]
