IP configuration overview
IP route exchange protocols
Brocade Layer 3 Switches support the following IP route exchange protocols:
• Routing Information Protocol (RIP)
• Open Shortest Path First (OSPF)
• Border Gateway Protocol version 4 (BGP4)
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 29, “RIP (IPv4)”
• Chapter 31, “OSPF version 2 (IPv4)”
• Chapter 33, “BGP (IPv4)”
IP multicast protocols
Brocade 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)
• Distance Vector Multicast Routing Protocol (DVMRP)
For configuration information, refer to Chapter 36, “IP Multicast Protocols”.
NOTE
Brocade Layer 2 Switches support IGMP and can forward IP multicast packets. Refer to Chapter 34,
“IP Multicast Traffic Reduction on Brocade FastIron X Series switches” and Chapter 35, “IP Multicast
Traffic Reduction for FastIron WS and Brocade FCX and ICX Switches”.
IP interface redundancy protocols
You can configure a Brocade Layer 3 Switch to back up an IP interface configured on another
Brocade 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.
Brocade 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 Brocade Layer 3 Switches and third-party routers to
back up IP interfaces on other Brocade Layer 3 Switches or third-party routers.
• Virtual Router Redundancy Protocol Extended (VRRP-E) – A Brocade extension to standard
VRRP that adds additional features and overcomes limitations in standard VRRP. You can use
VRRP-E only on Brocade Layer 3 Switches.
For configuration information, refer to the Chapter 39, “VRRP and VRRP-E”.
