Hey Guys,
I'm pretty confused on the topic of IP/UDP broadcast flooding and was
hoping someone could clarify. From my vague understanding of the topic,
you enable IP broadcast flooding by bridging router interfaces using
bridge groups on all interfaces that will support UDP flooding, as well
as configuring the ip forward-protocol [spanning-tree] command. My
question centers on the ip forward-protocol [spanning-tree] command.
Does this command ONLY enable the flooding of UDP broadcast traffic
specified (in ip forward-protocol udp) at the source network and prevent
any other IP traffic from passing through the bridge-group configured
interface or is this command used only to build a spanning-tree to avoid
loops in an environment in which one has multiple routers bridging on a
the same segments? I'm wondering if IP/UDP flooding is a specific
feature that's enabled with a sequence of commands, similar to the ip
helper-address command or is it just something that can be accomplished
manually through bridge-groups and filtering.
Can someone please clarify?
