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. |

Network Virtual Router Multicast Interfaces 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:
| Network Routing Routing Profiles Multicast Multicast IPv4 PIM Interface
Timer Profiles | The PIM interface timer is part of the multicast profile that
you can configure per interface.

- The legacy routing enginePermitted PIM Neighborsare migrated to theNeighbor Filterin the advanced routing engine.
- TheDR Priorityconfiguration range differs between the legacy and advanced routing engines.
