MLAG - PIM support

MLAG  - PIM Support

ExtremeXOS allows configuring PIM on both MLAG peers. PIM adjacencies between each MLAG vlan are established across the ISC link.

This synchronization is required because multicast traffic only sent to one of lag port as below.

• The checkpoint PIM state between MLAG peers. This should include all MLAG egresses.

• You can verify that PIM functionality for MLAG is present by issuing the following show command:

show pim cache {{detail} | {state-refresh} {mlag-peer-info} {group_addr}{source_addr}}

• Additionally, the existing show pim cache command displays ingress VLAN information for all MLAG peers.

The output of the command is shown below:

* core1.67 # show pim cache
