Suppressing RIP route advertisements on VRRP
backup devices
RIP route advertisement suppression can be enabled on VRRP backup devices to prevent other VRRP devices from learning multiple
paths for a backed-up interface.
A VRRP or VRRP-E session with master and backup devices must be configured and running.
Normally, a VRRP or VRRP-E backup includes route information for the virtual IP address (the backed-up interface) in RIP
advertisements. As a result, other devices receive multiple paths for the backed-up interface and might sometimes unsuccessfully use
the path to the backup device rather than the path to the master device.
You can prevent the backups from advertising route information for the backed-up interface by enabling suppression of the
advertisements.
NOTE
The command syntax is the same for VRRP and VRRP-E.
1. Enter the configure terminal command to access global configuration mode.
device# configure terminal
2. Enable RIP.
device(config)# router rip
3. Suppress RIP route advertisements.
device(config-rip-router)# use-vrrp-path
The following example suppresses RIP advertisements for the backed-up interface.
device# configure terminal
device(config)# router rip
device(config-rip-router)# use-vrrp-path
VRRP-Ev2 overview
VRRP Extended (VRRP-E) is an extended version of VRRP. VRRP-E is designed to avoid the limitations in the standards-based VRRP.
To create VRRP-E, Brocade has implemented the following differences from RFC 3768 which describes VRRPv2 to provide extended
functionality and ease of configuration:
• VRRP-E does not include the concept of an owner device, and a master VRRP-E is determined by the priority configured on
the device.
• While the VRRP-E virtual router IP address must belong in the same subnet as a real IP address assigned to a physical
interface of the device on which VRRP-E is configured, it must not be the same as any of the actual IP addresses on any
interface.
• Configuring VRRP-E uses the same task steps for all devices; there are no differences between master and backup device
configuration. The device configured with the highest priority assumes the master role.
VRRP-E is not supported on non-Brocade devices and does not interoperate with VRRP sessions on Brocade devices.
