BGP-3 Export Route Filter Parameter Descriptions
This section describes how to set all BGP-3 export route filter parameters.
Parameter: Export Address
Default: 0.0.0.0
Range: Any IP network address
Function: Identifies, by IP address, the network to which this filter applies. If this
field is left blank, the filter applies to all networks.
Instructions: Enter the appropriate network address in dotted decimal notation.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.1.15.1.3
Parameter: Export Mask
Default: 0.0.0.0
Range: Depends on the address class of the network address
Function: Specifies the range of addresses upon which this filter acts.
For example, consider Class B Network 172.32.0.0, which allocates the
upper 8 bits of the host identification field to the Subnet ID, and the final 8
bits to the Host ID. The address mask directs the filtering process to a
specific portion of the IP address. In other words, any IP address that
matches the masked portion of 172.32.0.0 is subject to filtering. If you
enter 255.255.0.0 for this parameter, only the Net ID portion of the
address will be filtered. If you enter the mask 255.255.255.0 for this
parameter, the Net ID and Subnet ID portions of the address will be
filtered.
