table { 1 | 2 }
: Specifies the Diameter host table to obtain the primary and secondary host names for
PCRF.

round-robin }
round-robin }
: Specifies the algorithm to select row from the Diameter host table.
Default:
round-robin
ip-address-modulus [ prefer-ipv4 | prefer-ipv6 ]
: This algorithm divides the IP address,
in binary, of the subscriber by the number of rows in the table, and the remainder is used as an index
into the specified table to select the row.
into the specified table to select the row.
prefer-ipv4: Specifies that IPv4 addresses are to be used, if an IPv4v6 call is received, for selecting the
rows in the host table.
prefer-ipv6: Specifies that IPv6 addresses are to be used, if an IPv4v6 call is received, for selecting the
rows in the host table.
msisdn-modulus
: This algorithm divides the MSISDN value in binary without the leading “+” of the
subscriber by the number of rows in the table, and the remainder is used as an index in the specific
table to select the row.
table to select the row.
round-robin
: This algorithm rotates all rows in the active table for selection of the row in round-robin
fashion. If no algorithm is specified this is the default behavior.
Important:
The Round Robin algorithm is effective only over a large number of selections, and not at a granular
level.
