from Statement Description
to Statement Description
interface
interface-name
Standard
Name or IP address of one or more routing
device interfaces. Do not use this qualifier
with protocols that are not
interface-specific, such as IBGP.
Name or IP address of one or more
routing device interfaces. Do not use this
qualifier with protocols that are not
interface-specific, such as IBGP.
Match a route learned from one of the
specified interfaces. Direct routes match
routes configured on the specified
interface.
Match a route to be advertised from one
of the specified interfaces.
internal
Standard
Match a routing policy against the internal flag for simplified next-hop self policies.
level level
Standard
(Intermediate System-to-Intermediate
System [IS-IS] only) IS-IS level.
Match a route learned from a specified
level.
(IS-IS only) IS-IS level.
Match a route to be advertised to a
specified level.
local-preference
value
Standard
(BGP only) BGP local preference (LOCAL_PREF) attribute. The preference value can
be a number in the range 0 through 4,294,967,295 (2 32 – 1).
metric metric metric2
metric metric3 metric
metric4 metric
Standard
Metric value. You can specify up to four metric values, starting with metric (for the
first metric value) and continuing with metric2, metric3, and metric4.
(BGP only) metric corresponds to the multiple exit discriminator (MED), and metric2
corresponds to the interior gateway protocol (IGP) metric if the BGP next hop runs
back through another route.
multicast-scoping
(scoping-name |
number) < (orhigher
| orlower) >
Standard
Multicast scope value of IPv4 or IPv6 multicast group address. The multicast-scoping
name corresponds to an IPv4 prefix. You can match on a specific multicast-scoping
prefix or on a range of prefixes. Specify orhigher to match on a scope and numerically
higher scopes, or orlower to match on a scope and numerically lower scopes. For more
information, see the Junos OS Multicast Protocols Configuration Guide.
You can apply this scoping policy to the routing table by including the scope-policy
statement at the [edit routing-options] hierarchy level.
The number value can be any hexadecimal number from 0 through F. The
multicast-scope value is a number from 0 through 15, or one of the following keywords
with the associated meanings:
• node-local (value=1)—No corresponding prefix
• link-local (value=2)—Corresponding prefix 224.0.0.0/24
• site-local (value=5)—No corresponding prefix
• global (value=14)—Corresponding prefix 224.0.1.0 through 238.255.255.255
• organization-local (value=8)—Corresponding prefix 239.192.0.0/14
