Overview
•
Open Shortest Path First (OSPF)
All these protocols provide routes to the IP route table. You can use one or more of these protocols,
in any combination. The protocols are disabled by default. For configuration information, refer to
the following:
•
•
Chapter 23, “Configuring OSPF Version 2 (IPv4)”
IP multicast protocols
Layer 3 Switches also support the following Internet Group Membership Protocol (IGMP) based IP
multicast protocols:
•
Protocol Independent Multicast – Dense mode (PIM-DM)
•
Protocol Independent Multicast – Sparse mode (PIM-SM)
For configuration information, refer to
Chapter 26, “Configuring IP Multicast Protocols”
.
NOTE
Layer 2 Switches support IGMP and can forward IP multicast packets. Refer to
“Configuring IP Multicast Traffic Reduction”
.
IP interface redundancy protocols
You can configure a Layer 3 Switch to back up an IP interface configured on another Layer 3
Switch. If the link for the backed up interface becomes unavailable, the other Layer 3 Switch can
continue service for the interface. This feature is especially useful for providing a backup to a
network default gateway.
Layer 3 Switches support the following IP interface redundancy protocols:
•
Virtual Router Redundancy Protocol (VRRP) – A standard router redundancy protocol based on
RFC 2338. You can use VRRP to configure Layer 3 Switches and third-party routers to back up
IP interfaces on other Layer 3 Switches or third-party routers.
•
Virtual Router Redundancy Protocol Extended (VRRP-E) – An extension to standard VRRP that
adds additional features and overcomes limitations in standard VRRP. You can use VRRP-E
only on Layer 3 Switches.
For configuration information, refer to the following:
•
Virtual Router Redundancy Protocol Extended (VRRP-E) – refer to
•
Virtual Router Redundancy Protocol (VRRP) – refer to
Chapter 27, “Configuring VRRP and
Access Control Lists and IP access policies
Layer 3 Switches provide two mechanisms for filtering IP traffic:
•
Access Control Lists (ACLs)
•
IP access policies
