preference preference — The preference of this static route versus the routes from different sources
metric metric — The cost metric for the static route, expressed as a decimal integer. When modifying
next-hop gateway — Specifies the directly connected next hop IP address used to reach the
7210 SAS M, X Router Configuration Guide
such as BGP or OSPF, expressed as a decimal integer. When modifing the preference of an
existing static route, the metric will not be changed unless specified.
Different protocols should not be configured with the same preference. If this occurs, the
tiebreaker is according to the default preference table defined in Table 3 on page 50
If multiple routes are learned with an identical preference using the same protocol, the lowest-
cost route is used. If multiple routes are learned with an identical preference using the same
protocol, and the costs (metrics) are equal, then the route to use is determined by the next-hop
with the lowest address.
Values 1 — 255
the metric of an existing static route, the preference will not change unless specified. This value
is also used to determine which static route to install in the forwarding table:
• If there are multiple static routes with the same preference but different metrics then the
lower cost (metric) route will be installed.
• If there are multiple static routes with equal preferences and metrics the route with the
lowest next-hop will be installed .
• If there are multiple routes with different preferences then the lower preference route
will be installed.

destination.If the next hop is over an unnumbered interface, the ip-int-name of the unnumbered
interface (on this node) can be configured.
The next-hop keyword and the black-hole keywords are mutually exclusive. If an identical
command is entered (with the exception of either the black-hole parameters), then this static
route will be replaced with the newly entered command, and unless specified, the respective
defaults for preference and metric will be applied.
The gateway configured here can be either on the network side or the access side on this node.
This address must be associated with a network directly connected to a network configured on
this node.
Values
ip-int-name
black-hole
Specifies the route is a black hole route. If the destination address on a packet matches this static
route, it will be silently discarded.
The black-hole keyword and the next-hop keyword are mutually exclusive. If an identical
command is entered (with the exception of either the next-hop parameter), then this static route
will be replaced with the newly entered command, and unless specified, the respective defaults
for preference and metric will be applied.
