Description
This feature was introduced on the Cisco 10000 series
router.
This feature was integrated into Cisco IOS Release 12.3(7)
XI1.
This feature was integrated into Cisco IOS Release
12.2(28)SB.
Cisco 10000 series router software does not support running Distance Vector Multicast Routing
Protocol (DVMRP) back to back between routers.
If you enable IP multicast fast switching on one interface, you must enable it on all outbound
interfaces on the router. Failure to do so results in the router sending duplicate multicast packets out
the interface that has fast switching enabled.
Cisco 10000 series router does not support accounting for Multicast packets on Packet over SONET
(POS) line cards, Gigabit Ethernet subinterfaces, and ATM AAL5 layer type.
The Cisco 10000 series router does not support fragmentation of multicast traffic.
The Cisco 10000 series router does not support fragmentation on Multicast Distribution Tree
(MDT). To avoid fragmentation, we recommend that the value of MDT Maximum Transmission
Unit (MTU) is set to a maximum of 64000.
