IP Router Configuration
7750 SR OS Router Configuration Guide
Page 125
The
ip-address
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
32 chars max
ipv4-address
a.b.c.d
ipv6-address
x:x:x:x:x:x:x:x[-interface]

x: [0..FFFF]H
d: [0..255]D
interface: 32 characters maximum, mandatory for link local
addresses
indirect
ip-address
—
Specifies that the route is indirect and specifies the next hop IP address used to
reach the destination.
The configured
ip-addr
is not directly connected to a network configured on this node. The
destination can be reachable via multiple paths. The indirect address can only resolved from
dynamic routing protocol. Another static route cannot be used to resolve the indirect address.
The
indirect
keyword and the
next-hop
or
black-hole
keywords are mutually exclusive. If an
identical command is entered (with the exception of either the
next-hop
or
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
ip-addr
configured can be either on the network or the access side and is normally at least
one hop away from this node.
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
or
indirect
keywords are mutually exclusive. If an
identical command is entered (with the exception of either the
next-hop
or
indirect
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.
disallow-igp —
This value is valid only for indirect static routes. If set and if none of the defined
tunneling mechanisms (RSVP-TE, LDP or IP) qualify as a next-hop, the normal IGP next-hop to
the indirect next-hop address will not be used. If not set then the IGP next-hop to the indirect
next-hop address can be used as the next-hop of the last resort.
tag —
Adds a 32-bit integer tag to the static route. The tag is used in route policies to control
distribution of the route into other protocols.
