IP multicast enhancements (Continued)
Description
Embedded RP allows the router to learn RP
information using the multicast group
destination address instead of the statically
configured RP.
IPv6 PIM SM provides the Multicast IP Sparse
Mode protocol for routing multicast packets to
multicast groups. It is designed to efficiently
establish distribution trees across wide area
networks where multicast groups are thinly
populated across a large region.
IP service, security, and Layer 4 enhancements
Description
This is a security feature that allows a port to
run STP but not allow the connected device to
become the Root.
BPDU Guard is an extension to the port fast
feature. If a port is in port fast mode of
operation and a BDPU is received, the port is
put into the disabled mode.
This feature provides protection against
physical link instability. It allows a user to
configure it to keep a port in a down state in
cases where the port has experienced some
number of state transitions within a configured
amount of time.
You can allow a DHCP client to send a message
to a DHCP server by using a DHCP relay agent.
