# passive-interface

#### Syntax

IS-IS:

passive-interface interfaceType interfaceSpecifier [ tag tagValue ]
[ metric metricValue [ level-1 | level-2 ] ]

no passive-interface interfaceType interfaceSpecifier [ tag ] [ metric [ level-1 |
level-2 ] ]

OSPF and RIP:

[ no ] passive-interface interfaceType interfaceSpecifier

#### Release Information

Command introduced before JunosE Release 7.1.0.
metric keyword and metricValue variable for IS-IS added in JunosE Release 9.0.0.

#### Description

Modifies the transmission of routing updates for IS-IS, OSPF, and RIP.

For IS-IS, configures an IS-IS interface only to advertise its IP address in the link-state PDUs; the interface does not send or receive IS-IS packets. Issue the complementary interface command to enable the interface to send and receive IS-IS packets. Optionally, you can set a route tag value for the IP addresses on an IS-IS passive interface before the route is propagated to other routers in an IS-IS domain. You can set a metric value for the passive interface; the default value is 0. The no version disables advertisement of the IP address, or unconfigures the tag, the metric, or both.

For OSPF, halts the transmission of routing updates on an OSPF interface. OSPF neither sends nor receives routing information through the specified interface, which appears as a stub network in the OSPF network. The no version reenables the transmission of routing updates.

For RIP, halts the transmission of multicast RIP messages. RIP messages are unicast to the interface (if it is the best path to a configured neighbor). The no version reenables the transmission of multicast messages on the interface.

#### Options

- interfaceType—Interface type; see Interface Types and Specifiers
- interfaceSpecifier—Particular interface; format varies according to interface type; see Interface Types and Specifiers
- tagValue—Number, in the range 1–4294967295, that identifies the route tag assigned to the IS-IS passive interface
- metricValue—Metric used when advertising the passive interface; in the range 1–16777215; default value is 0

#### Mode

Address Family Configuration (RIP), Router Configuration (IS-IS, OSPF, RIP)
