PIM

Protocol Independent Multicast (PIM) routing protocol configuration parameter differences between legacy and advanced routing engine.

There are parameter setting differences between legacy and advanced routing engines when configuring Protocol Independent Multicast (PIM) settings.

Migration Exception:

During migration, each entry in the access list is replaced with a sequence number.
While a legacy routing engine can apply group permissions on specific interfaces, the advanced routing engine applies group permissions only globally. As a result, any interface-specific PIM group permissions on the legacy routing engine are not migrated to the advanced routing engine.

LEGACY ROUTING ENGINE	ADVANCED ROUTING ENGINE
A legacy routing engine refers to group permissions by name. This applies to both source-specific and non-source specific (any source) entries.	The advanced routing engine uses extended access lists as filters. Each entry in these access lists uses a sequence number instead of a name. As a result, the entry names are lost and are replaced by a sequence number in the access list during the migration.
A legacy routing engine can apply group permissions to specific interfaces.	The advanced routing engine can apply group permissions only globally—not to specific interfaces. Therefore, any interface-specific PIM group permissions configured on the legacy routing engine are not migrated.

PIM Timers

Migration Exception: The configurable values of interface timers vary between the legacy and advanced routing engines.

CONFIGURED IN (LEGACY ROUTING ENGINE)	LEGACY ROUTING ENGINE	MIGRATED TO (ADVANCED ROUTING ENGINE)	ADVANCED ROUTING ENGINE
NetworkVirtual RouterMulticastInterfaces PIM	Specifies only a global set of timers for each function. These timers are applied to all interfaces participating in the PIM routing domain. PIM parameters for interface group: Assert Interval—Specifies the interval (in seconds) between PIM Assert messages to elect a PIM Forwarder (range is 0 to 65,534; default is 177). Hello Interval—Specifies the interval (in seconds) between PIM Hello messages (range is 0 to 18,000; default is 30). Join Prune Interval—Specifies the number of seconds between the two PIM-Join messages and between two PIM-Prune messages (range is 1 to 18,000; default is 60).	NetworkRoutingRouting ProfilesMulticast Multicast IPv4 PIM Interface Timer Profiles	The PIM interface timer is part of the multicast profile that you can configure per interface. Assert Interval—Specifies the interval (in seconds) between PIM Assert messages to elect a PIM Forwarder (range is 1 to 65,534; default is 177). Hello Interval—Specifies the interval (in seconds) between PIM Hello messages (range is 1 to 180; default is 30). A legacy routing range configured with a value greater than 180 is changed during migration to a value supported by the advanced routing engine. Join Prune Interval—Specifies the number of seconds between PIM Join messages and between PIM Prune messages (range is 60 to 600; default is 60). A legacy routing range configured with a value greater than 600 is changed during migration to a value supported by the advanced routing engine.

PIM - Multicast Interfaces

Migration Exception:

The legacy routing engine BSR Border settings are migrated to the Send BSM settings in the advanced routing engine.
The legacy routing engine Permitted PIM Neighbors are migrated to the Neighbor Filter in the advanced routing engine.
The DR Priority configuration range differs between the legacy and advanced routing engines.

CONFIGURED IN (LEGACY ROUTING ENGINE)	LEGACY ROUTING ENGINE	MIGRATED TO (ADVANCED ROUTING ENGINE)	ADVANCED ROUTING ENGINE
NetworkVirtual RouterMulticastInterfaces PIM	PIM configuration parameters for multicast interfaces: BSR Border—Enables use of the interface as the bootstrap border. Permitted PIM Neighbors—Specifies the list of neighbors that can communicate using PIM. DR Priority—Specifies the designated router priority for an interface group (range is 0 to 4,294,967,295; default is 1).	NetworkRoutingLogical RoutersMulticast PIM - Interfaces	PIM configuration parameters for multicast interfaces: Send BSM—Enables propagation of Bootstrap Messages (enabled by default). Neighbor Filter—Specifies the access list that determines the prefixes of devices that are or are not allowed to become PIM neighbors of the logical router (default is none—no access list). DR Priority—Specifies the designated router priority for an interface group (range is 1 to 4,294,967,295; default is 1).
