multihoming
Syntax [ no ] multihoming primary|secondary [ hold-time holdover-time ]
Context config>router>interface
Description This command sets the associated loopback interface to be an anycast address used in multi-homing
resiliency, as either the primary or a secondary (a primary address on the alternate router). The
optional hold-time parameter is only applicable for the secondary context and specifies how long
label information learned about the secondary anycast address should be kept after that peer is
declared down. This timer should be set to a value large enough for the remainder of the network to
detect the failure and complete the reconvergence process.
The no form of the command disables this setting.
Default no multihoming
Parameters
holdover-time — Specifies the number of seconds the router should hold label information learned
from the alternate router in its secondary table. This is to allow the reset of the network to
reconverge after a router failure before the anycase based label assignments are flushed from the
forwarding plane.
Values
0 - 65535
Default
90
network-domain
Syntax network-domain network-domain-name
no network-domain
Context config>router>interface
Description
This command assigns a given interface to a given network-domain. The network-domain is then
taken into account during sap-ingress queue allocation for VPLS SAP.
The network-domain association can only be done in a base-routing context. Associating a network
domain with an loop-back or system interface will be rejected. Associating a network-domain with an
interface that has no physical port specified will be accepted, but will have no effect as long as a
corresponding port, or LAG, is defined..
Single interfaces can be associated with multiple network-domains.
Default
per default “default” network domain is assigned
ntp-broadcast
Syntax [ no ] ntp-broadcast
Context config>router>interface
Description
This command enables SNTP broadcasts received on the IP interface. This parameter is only valid
when the SNTP
broadcast-client global parameter is configured.
