Foundry Networks Switch and Router User Manual

Configuring BGP4
December 2000 19 - 71
Switch does not already have explicit routing information for the traffic. This option is used in Policy-Based
Routing (PBR). See “Policy-Based Routing (PBR)” on page 13-25.
The local-preference <num> parameter sets the local preference for the route. You can set the preference to a
value from 0 – 4294967295.
The metric [+ | - ]<num> | none parameter sets the MED (metric) value for the route. The default MED value is 0.
You can set the preference to a value from 0 – 4294967295.
• set metric <num> – Sets the route’s metric to the number you specify.
• set metric +<num> – Increases route’s metric by the number you specify.
• set metric -<num> – Decreases route’s metric by the number you specify.
• set metric none – Removes the metric from the route (removes the MED attribute from the BGP4 route).
The next-hop <ip-addr> parameter sets the IP address of the route’s next hop router.
The origin igp | incomplete parameter sets the route’s origin to IGP or INCOMPLETE.
The tag <tag-value> parameter sets the route’s tag. You can specify a tag value from 0 – 4294967295.
NOTE: This parameter applies only to routes redistributed into OSPF.
NOTE: You also can set the tag value using a table map. The table map changes the value only when the Layer
3 Switch places the route in the IP route table instead of changing the value in the BGP route table. See “Using a
Table Map To Set the Tag Value” on page 19-72.
The weight <num> parameter sets the weight for the route. You can specify a weight value from
0 – 4294967295.
USING THE WEB MANAGEMENT INTERFACE

the option inactive.
