Configuring Redundancy 27
Chapter 4
In the network shown above, the master switch is layer 2 connected to the
local switches on VLANs 1, 2… n respectively. To configure redundancy as
described in the conceptual overview for master-local redundancy, configure
VRRP instances on each of the VLANs between the master and the respective
local switch. The VRRP instance on the local switch is configured with a
higher priority to ensure that when available, the APs always choose the local
switch to terminate their tunnels.
To configure the master and local switches for such a topology:
1. Configure the interface on the master switch to be a trunk port with 1, 2…
n being member VLANs. Refer to the “Configuring Network Parameters” for
more details on how to configure this.
2 Collect the following data before configuring master switch redundancy.
z VLAN IDs on the switches corresponding to the VLANs 1, 2…n shown
in the topology above.
z Virtual IP addresses that has been reserved to be used for the VRRP
instances.
3 Connect to the switch CLI using Telnet or SSH. After logging into the
switch, enter the global configuration mode.
