Suppressing RIP advertisement from backups
Normally, for Layer 3 a VSRP Backup includes route information for a backed up IP address in RIP
advertisements. As a result, other Layer 3 Switches receive multiple paths for the backed up interface
and might sometimes unsuccessfully use the path to the Backup rather than the path to the Master.
You can prevent the Backups from advertising route information for the backed up interface by
enabling suppression of the advertisements.
NOTE
This parameter applies only if you specified an IP address to back up and is valid only on Layer 3
Switches.
To suppress RIP advertisements, enter the following commands.
device(config)#router rip
device(config-rip-router)#use-vrrp-path
Syntax: [no] use-vrrp-path
VSRP-aware interoperablilty
The vsrp-aware tc-vlan-flush command should be used in network configurations in which the
Brocade switch operates as the VSRP-Aware device connecting to a FastIron platforms configured as
a VSRP Master.
The command is available at the VLAN level, and is issued per a specific VRID, as shown here for
VRID 11.
device(config-vlan-10)#vsrp-aware vrid 11 tc-vlan-flush
Syntax: vsrp-aware vrid num tc-vlan-flush
When this command is enabled, MAC addresses will be flushed at the VLAN level, instead of at the
port level. MAC addresses will be flushed for every topology change (TC) received on the VSRP-
aware ports.
When you configure the vsrp-aware tc-vlan-flush command on a VSRP-aware device, and the
device receives VSRP hello packets from the VSRP master, VSRP authentication is automatically
configured. However, if the VSRP-aware device does not receive VSRP hello packets from the VSRP
master when the vsrp-aware tc-vlan-flush command is configured, you must manually configure
VSRP authentication. For more information on configuring VSRP authentication, refer to
Configuring
authentication on page 106.
When this command is enabled, the results of the show vsrp-aware vlan command resemble the
following.
device(config-vlan-10)#vsrp-aware vrid 11 tc-vlan-flush
device(config-vlan-10)#show vsrp aware vlan 10
