VPRN Service Configuration Commands
mc-ecmp-balance-hold
Syntax mc-ecmp-balance-hold minutes
no mc-ecmp-balance-hold
Context config>service>vprn>pim
Description This command configures the hold time for multicast balancing over ECMP links.
Parameters
minutes — Specifies the hold time, in minutes, that applies after an interface has been added to the
non-dr-attract-traffic
Syntax [no] non-dr-attract-traffic
Context config>service>vprn>pim
Description This command specifies whether the router should ignore the designated router state and attract traffic
even when it is not the designater router.
An operator can configure an interface (router or IES or VPRN interfaces) to IGMP and PIM. The
interface IGMP state will be synchronized to the backup node if it is associated with the redundant
peer port. The interface can be configured to use PIM which will cause multicast streams to be sent to
the elected DR only. The DR will also be the router sending traffic to the DSLAM. Since it may be
required to attract traffic to both routers a flag non-dr-attract-trafffic can be used in the PIM context to
have the router ignore the DR state and attract traffic when not DR. Note that while using this flag the
router may not send the stream down to the DSLAM while not DR.
When enabled, the designated router state is ignored. When disabled, no non-dr-attract-traffic, the
designated router value is honored.
Default
no non-dr-attract-traffic
rp
Syntax rp
Context config>service>vprn>pim
Description This command enables access to the context to configure the rendezvous point (RP) ) of a PIM
protocol instance.
An Alcatel-Lucent PIM router acting as an RP must respond to a PIM register message specifying an
SSM multicast group address by sending to the first hop router stop register message(s). It does not
build an (S, G) shortest path tree toward the first hop router. An SSM multicast group address can be
either from the SSM default range of 232/8 or from a multicast group address range that was
explicitly configured for SSM.
Default rp enabled when PIM is enabled.
