# The rt_ereg extension allows creation of routing rules based on AVP value matching regular expressions.

# This extension supports configuration reload at runtime. Send
# signal SIGUSR1 to the process to cause the process to reload its
# config.

# First, one must indicate which AVP should be used for matching. 
# At the moment, only AVP with OCTETSTRING types are valid.
#  AVP = "User-Name";
# It is possible to specify AVPs below GROUPED AVPs with the by separating AVPs with a colon (':'):
#  AVP = "Grouped-AVP1" : "Grouped-AVP2" : "Octetstring-AVP";
# This parameter is mandatory. There is no default value.

# Then a list of rules follow. A rule has this format:
#  "pattern" : "server" += score ;
# Where:
#  pattern is the quoted-string regex to match, 
#  server is the next hop in the routing list that will receive the
#  score, which can be positive or negative.
# Example:
#  "[[:digit:]]*" : "serverA.example.net" += -3 ;
#    means that if the AVP value is only numeric, the ServerA will have its score decreased by 3 points.
#    (reminder: the server with the peer with the highest score gets the message)
# Note that all rules are tested for each message that contain the AVP, not only the first match.

# There can be multiple blocks of AVPs and rules; just start the next one with another AVP line:
#  AVP = "Other-AVP";
# and continue with rules as above.
