Re-Importing Routing Rules
To be change routing rules, Route.dic will need to be modified, and then re-imported.
When routing rules are re-imported:
ƒ The existing routing table will be replaced. Retaining the original set of rules in a
backup file allows you to restore the routing table, if necessary.
ƒ If you are using load balancing, importing routing rules will cause internal counters
that control load balancing to be reset. For more information, see page 13 .
ƒ If multiple Routing Gateways are present, the steps for importing the modified rules
file must be performed for all Routing Gateways, so that Gateways will all use the
same set of rules.
Routing Rules & Multiple Routing Gateways
If multiple evaluation processors need to be active (as could be the case at a consolidated
site) each Routing Gateway can use its own local set of rules.
However, it is usually better for all Routing Gateways to use a single set of rules stored in
a shared directory. Using the same set of rules will make maintenance easier (changes to
rules need to be made in only one
Route.dic file, rather than several), and allows each
gateway in the pool to function as a backup for any other gateway.
