Conditions: !smips
Type: Directory

The instance menu defines the main PIM-SM settings. The instance is then used for all other PIM-related configurations like interface-template, static RP, and Bootstrap Router.

FlagNameDescription
Xdisableddisabled
Iinactiveinactive
ArgumentTypeDescription
vrfenumName of the VRF for control connections.
namestringName of the instance.
afienum (ip | ipv6)Specifies address family for PIM.
switch-to-sptboolWhether to switch to Shortest Path Tree (SPT) if multicast data bandwidth threshold is reached. The router will not proceed from protocol phase one (register encapsulation) to native multicast traffic flow if this option is disabled. It is recommended to enable this option.
switch-to-spt-intervaltimeTime interval in which to account for multicast data bandwidth, used in conjunction with switch-to-spt-bytes to determine if the switching threshold is reached.
switch-to-spt-bytesnumMulticast data bandwidth threshold. Switching to Shortest Path Tree (SPT) happens if this threshold is reached in the specified time interval. If a value of 0 is configured, switching will happen immediately.
crp-advertise-containedboolCurrently not implemented.
bsm-forward-backboolCurrently not implemented.
rp-hash-mask-lengthnumThe hash mask allows changing how many groups to map to one of the matching RPs.
rp-static-overrideboolChanges the selection priority for static RP. When disabled, the bootstrap RP set has a higher priority. When enabled, static RP has a higher priority.
ssm-rangeaddress (flags=46/)Currently not implemented.

routing/pimsm/interface-template

Conditions: !smips
Type: Directory

The interface template menu defines which interfaces will participate in PIM and what per-interface configuration will be used.

FlagNameDescription
Xdisableddisabled
Iinactiveinactive
ArgumentTypeDescription
instance ( mandatory )enumName of the PIM instance this interface template belongs to.
interfaces ( unset )obj_arg { interface_enum { } { } }List of interfaces that will participate in PIM.
hello-periodtimePeriodic interval for Hello messages.
hello-delaytimeRandomized interval for the initial Hello message on interface startup or detecting a new neighbor.
prioritynumThe Designated Router (DR) priority. A single Designated Router is elected on each network. The priority is used only if all neighbors have advertised a priority option. The numerically largest priority is preferred. In case of a tie or if priority is not used - the numerically largest IP address is preferred.
join-prune-periodtime
propagation-delaytimeSets the value for a prune pending timer. It is used by upstream routers to figure out how long they should wait for a Join override message before pruning an interface that has join suppression enabled.
override-intervaltimeSets the maximum time period over which to randomize when scheduling a delayed override Join message on a network that has join suppression enabled.
join-tracking-supportboolSets the value of a Tracking (T) bit in the LAN Prune Delay option in the Hello message. When enabled, a router advertises its willingness to disable Join suppression. It is possible for upstream routers to explicitly track the join membership of individual downstream routers if Join suppression is disabled. Unless all PIM routers on a link negotiate this capability, explicit tracking and the disabling of the Join suppression mechanism are not possible.
source-addresses ( unset )obj_arg { address (flags=46) }

Read-only ArgumentTypeDescription

addressaddress (flags=46i)Shows the neighbor's IP address and local interface the neighbor is detected on.
prioritynumIndicates the neighbor's priority value.
timeouttimeShows the remaining time after the neighbor is removed from the list if no new Hello message is received. The hold time equals neighbor's hello-period * 3.5.
designated-routerboolShows whether the neighbor is elected as Designated Router (DR).
propagation-delaytimeIndicates the neighbor's value of the propagation delay in the LAN Prune Delay option in the Hello message.
override-intervaltimeIndicates the neighbor's value of the override interval in the LAN Prune Delay option in the Hello message.
join-trackingboolIndicates the neighbor's value of a Tracking (T) bit in the LAN Prune Delay option in the Hello message.

routing/pimsm/static-rp

Conditions: !smips
Type: Directory

The static-rp menu allows manually defining the multicast group to RP mappings. Such a mechanism is not robust to failures but does at least provide a basic interoperability mechanism.

ArgumentTypeDescription
instance ( mandatory )enumThe name of the PIM instance this static RP belongs to.
groupaddress (flags=46/)The multicast group that belongs to a specific RP.
addressaddress (flags=46)The IP address of the static RP.

routing/pimsm/uib-g

Conditions: !smips
Type: Directory

The upstream information base menus show the any-source multicast (*,G) and source-specific multicast (S,G) groups and their statuses. These menus contain only read-only entries.

FlagNameDescription
Rrp-localrp-local
Read-only ArgumentTypeDescription
instanceenumName of the PIM instance the multicast group is created on.
groupaddress (flags=46i)The multicast group address.
rpaddress (flags=46i)The address of the Rendezvous Point for this group.
rpfaddress (flags=46i)The Reverse Path Forwarding (RPF) indicates the router address and outgoing interface that a Join message for that group is directed to.
rp-localboolIndicates whether the multicast router itself is the RP.

routing/pimsm/uib-sg

Conditions: !smips

missing spt-bit The Shortest Path Tree (SPT) bit indicates whether forwarding is taking place on the (S,G) Shortest Path Tree or on the (*,G) tree. A router can have an (S,G) state and still be forwarding on a (*,G) state during the interval when the source-specific tree is being constructed. When the SPT bit is false, only the (*,G) forwarding state is used to forward packets from S to G. When the SPT bit is true, both (*,G) and (S,G) forwarding states are used.
