Overview of VRRP
If there is no manually configured virtual MAC address for a VRRP instance, the system
automatically assigns one.
For Brocade NetIron CES and Brocade NetIron CER platforms, you can configure a maximum of
255 virtual MAC addresses.
This feature is subject to the following limitations:
• This feature does not support configurable VRRP virtual MAC addresses over MCT.
• This feature has no impact on short-path forwarding for VRRP-E.
NOTE
System-assigned virtual MAC addresses and manually configured virtual MAC addresses can exist
at the same time on the device under the same VRID, however the configured value takes
precedence. When the configured value is deleted, the assigned value again applies.
To configure a unique VRRP or VRRP-E virtual MAC address for a VRID, complete the following
steps.
1. To configure an IPv4 virtual MAC address for VRID 1 (for example), enter the following
command at the configure VRID level of the CLI:
Brocade(config-if-e1000-1/110-vrid-1)virtual-mac aaaa.bbbb.cccc
Syntax: [no] virtual-mac mac-address
Use the no version of this command to remove the configured address.
2. To configure an IPv6 virtual MAC address for VRID 1 (for example), enter the following
command at the configure VRID level of the CLI:
Brocade(config-if-e1000-1/110-ipv6-vrid-1)virtual-mac aaaa.bbbb.cccc
Syntax: [no] virtual-mac ipv6 mac-address
Use the no version of this command to remove the configured address.
3. To display IPv4 VRRP virtual MAC address configuration information about VRID 1 (for
example), enter the following command:
Brocade#show ip vrrp vrid 1
