ExtremeWare XOS 11.5 Command Reference Guide
1873
configure mld snooping flood-list
configure mld snooping flood-list [<policy> | none]
Description
Configures certain multicast addresses to be slow path flooded within the VLAN.
Syntax Description
Default
None.
Usage Guidelines
With this command, a user can configure certain multicast addresses to be slow path flooded within the
VLAN, which otherwise will be fast path forwarded according to MLD and/or layer 3 multicast
protocol.
A policy file is a text file with the extension .pol. It can be created or edited with any text editor. The
specified policy file
<policy file>
should contain a list of addresses which will determine if certain
multicast streams are to be treated specially. Typically, if the switch receives a stream with a destination
address which is in the
<policy file>
in 'permit' mode, that stream will be software flooded and no
hardware entry would be installed.
When adding an IPv6 address into the policy file, a 128-bit host address is recommended.
This feature is meant to solve the multicast connectivity problem for unknown destination addresses
within system reserved ranges. Specifically this feature was introduced to solve the problem of
recognizing certain stream as control packets.
To create a policy file for the snooping flood-list, use the following template:
#
# This is a template for MLD Snooping Flood-list Policy File
# Add your group addresses between "Start" and "End"
# Do not touch rest of file!!!!
entry mldFlood {
if match any {
#------------------ Start of group addresses ------------------
nlri ff05::100:1/128;
nlri ff05::100:15/128;
#------------------- end of group addresses -------------------
} then {
permit;
}
policy
