SIP User's Manual 10. Networking Capabilities
10.8.2.2.5 Metric Column
The Metric column must be set to 1 for each routing rule.
10.8.2.3 Routing Table Configuration Summary and Guidelines
The Routing table configurations must adhere to the following rules:

Up to 25 different routing rules may be defined.

T

If both "Prefix Length" and "Subnet Mask" are defined, the "Prefix Length" overrides
the "Subnet Mask".
he user may choose whether to specify "Prefix Length" or "Subnet Mask". There is no
need to specify both.

The "Gateway" IP Address must be available on one of the local subnets.

The "Interface" column must be set to the Interface that the "Gateway" is configured
on.

The "Metric" column must be set to 1.

The Routing Table configuration, unlike the Multiple Interface table configuration is
online. Therefore, the changes made to the routing rules are applied immediately.
10.8.2.4 Troubleshooting the Routing Table
When adding or modifying any of the routing rules, the added or modified rule passes a
validation test. If errors are found, the route is rejected and is not added to the Routing
table. Failed routing validations may result in limited connectivity (or no connectivity) to the
destinations specified in the incorrect routing rule. For any error found in the Routing table
or failure to configure a routing rule, the device sends a notification message to the Syslog
server reporting the problem.
Common routing rule configuration errors may include the following:

The IP address specified in the "Gateway" column is unreachable from the interface
specified in the "Interface" column.

The same destination is defined in two different routing rules.

"Subnet Mask" and "Prefix Length" columns are both entered with inconsistent values,
and the "Prefix Length" overrides the "Subnet Mask" column.

More than 25 routing rules were specified.
Note: If a routing rule is required to access OAMP applications (for remote
management, for instance) and this route is not configured correctly, the route
is not added and the device is not accessible remotely. To restore
connectivity, the device must be accessed locally from the OAMP subnet and
the required routes be configured.
