VRRP and VRRP-E
Table 275 lists the individual Brocade FastIron switches and the Virtual Router Redundancy
Protocol (VRRP) and Virtual Router Redundancy Protocol Extended (VRRP-E) features they support.
NOTE
VRRP is supported in the base Layer 3, edge Layer 3, and full Layer 3 codes. VRRP support in the
base Layer 3 and edge Layer 3 code is the same as in the full Layer 3 code. VRRP-E is supported
with premium and ADV FastIron devices that are running the edge Layer 3 or full Layer 3 code.
* Refers to support for only IPv6 modules for these devices.
This chapter describes how to configure Brocade Layer 3 switches with the following router
redundancy protocols:
• Virtual Router Redundancy Protocol (VRRP) – The standard router redundancy protocol
described in RFC 2338. The FastIron devices support VRRP version 2 (v2) and VRRP version 3
(v3). VRRP v2 supports the IPv4 environment, and VRRP v3 supports the IPv6 environment.
• VRRP Extended (VRRP-E) – An enhanced version of VRRP that overcomes limitations in the
standard protocol. The FastIron devices support VRRP-E v2 and VRRP-E v3. VRRP-E v2
supports the IPv4 environment, and VRRP-E v3 supports the IPv6 environment.
NOTE
VRRP and VRRP-E are separate protocols. You cannot use them together.
