Sorry... Here is the full article:
Procedure:
Option conserves usage of the hardware Layer 3 multicast forwarding table:
configure igmp snooping filters per-vlan
(to set it back to default set it to per-port)
After changing the IGMP snooping filters from per-port (default) to per-vlan you can disable IGMP snooping on VLAN's where IGMP snooping is not required:
disable igmp snooping vlan
Stores multicast entries in the format (* AnySourceIP, GroupIP, VlanId), which is also referred to as (*, G):
configure igmp snooping forwarding-mode group-vlan
(to set it back to default configure it to source-group-vlan)
Routes with longer network masks might not be necessary if they are a subset of other routes with shorter network masks using the same gateway(s). When IP route compression is enabled, these unnecessary routes are not provided to the Forwarding information Base (FIB).
enable iproute compression
Additional notes:
Beginning in EXOS 15.4, the command configure igmp snooping forwarding-mode group-vlan was replaced with configure forwarding ipmc lookup-key group-vlan.
Hope it helps!
