next-hop-group (Forwarding Options)

Syntax for Routers

Syntax for EX3400, EX4100, EX4100-F, EX4300-MP, and EX4400 Switches

Hierarchy Level

Description

Specify the next-hop address for sending copies of packets to an analyzer.

(This paragraph applies only to routers.) The commit operation fails when a next-hop group has only one interface configured. It is implicitly assumed that a subgroup is up only if more than one interface in the subgroup is up.

Note:

(This Note applies only to routers.) In Junos OS releases earlier through Release 14.2, the next-hop-group statement is present in the forwarding-options stanza for a routing instance, but the next-hop-group statement is not allowed in a routing instance. In other words, in a routing instance, [edit routing-instances routing-instance-name forwarding-options next-hop-group] is not supported. You will get an error message if you try to commit this type of configuration. Starting in Junos OS Release 14.2, the next-hop-group statement is not present in [edit routing-instances routing-instance-name forwarding-options].

Options

interface interface-name

Name of interface used to reach the next-hop destination.

group-type layer-2

(Applies only to EX switches) Group type of the next-hop group. The allowed value for group-type is layer-2.

next-hop address

(Applies only to routers) IP address of the next-hop router. Each next-hop group supports up to 16 next-hop addresses. Up to 30 next-hop groups are supported. Each next-hop group must have at least two next-hop addresses.

next-hop-group group-name

Name of the next-hop group. The next-hop group can contain Layer 2 members, Layer 3 members, and subgroups that are either unit list (mirroring packets to each interface) or load-balanced (mirroring packets to one of several interfaces).

  • Routers—Up to 30 next-hop groups are supported. Each next-hop group must have at least two next-hop addresses.

  • Switches—Up to 4 next-hop groups are supported.

next-hop-subgroup subgroup-name

Name of a next-hop subgroup. Subgroups are either unit list (mirroring packets to each interface) or load-balanced (mirroring packets to one of several interfaces)
