PIM-DM DT

PIM-DM DT is not VLAN specific. PIM-DM DT can be configured on any VLAN to enable PIM-DM DT. For more information, see Distributed Trunking chapter in the Management and Configuration Guide of your switch.

  • When PIM-DM DT are enabled, the feature is in place.

  • PIM-SM can be configured with DT.

  • v1 modules must be disabled prior to PIM-DM DT. Module v1 is available with either feature individually but not when enabled together. Use the [no] allow-v1-modules command to disable V1 modules. If PIM-DM DT is enabled first, a v1 module will fail.

  • With v1 modules allowed, PIM and DT must be configured as a first configuration.

  • In multiple VLANs, the configurations can be in combinations of DT and PIM-DM. The PIM-DM DT feature must be enabled on first combination of PIM-DM DT and disabled when the last pair is un-configured. There can be multiple such pairs but each is not strictly bound to the same VLAN.

For information on the [no] allow-v1-modules command, see the Management and Configuration Guide for your switch.

NOTE:

DT trunks can use jumbo VLAN as usual, but user needs to ensure that jumbo is configured on both the DT pairs, otherwise packet drops/fragmentations can be seen.
