Values

exclusive

When this option is specified, the addresses configured are exclusively used for services and
cannot be assigned to network ports.

triggered-policy

Syntax

triggered-policy
no triggered-policy

Context

config>router

Description

This command triggers route policy re-evaluation.

By default, when a change is made to a policy in the config router policy options context and then
committed, the change is effective immediately. There may be circumstances when the changes
should or must be delayed; for example, if a policy change is implemented that would affect every
BGP peer on a 7750 SR router, the consequences could be dramatic. It would be more effective to
control changes on a peer-by-peer basis.

If the triggered-policy command is enabled, and a given peer is established, and you want the peer to
remain up, in order for a change to a route policy to take effect, a clear command with the soft or soft
inbound
option must be used; for example, clear router bgp neighbor x.x.x.x soft. This keeps the
peer up, and the change made to a route policy is applied only to that peer or group of peers.

static-route

Syntax

[no] static-route {ip-prefix/prefix-length | ip-prefix netmask} [preference preference]
[metric metric] [tag tag] [enable | disable] next-hop ip-int-name|ip-address [mcast-ipv4]
[no] static-route {ip-prefix/prefix-length | ip-prefix netmask} [preference preference]
[metric metric] [tag tag] [enable | disable] indirect ip-address [ldp [disallow-igp]]
[no] static-route {ip-prefix/prefix-length | ip-prefix netmask} [preference preference]
[metric metric] [tag tag] [enable | disable] black-hole [mcast-ipv4]

Context

config>router

Description

This command creates static route entries for both the network and access routes.
When configuring a static route, either next-hop, indirect or black-hole must be configured.
The no form of the command deletes the static route entry. If a static route needs to be removed when
multiple static routes exist to the same destination, then as many parameters to uniquely identify the
static route must be entered.

Default

No static routes are defined.

Parameters

ip-prefix/prefix-length — The destination address of the static route.

Values

ipv4-prefix a.b.c.d

(host bits must be 0)

ipv4-prefix-length

0 — 32

ipv6-prefix

x:x:x:x:x:x:x:x (eight 16-bit pieces)
