High Availability
The key to hot standby is that the interswitch link does not participate in STP, so there are no loops
in the topology (see Hot Standby Configuration, page
the VRRR hot standby scenario.
Note: In a host-standby configuration, Radware recommends that you locate the server and the
interswitch link on the same VLAN. This ensures that services are in the UP state for both the master
as well as the backup.
The following procedures refer to
• To configure Layer 2 and Layer 3 parameters on Alteon 1, page 538
• To configure virtual router redundancy, page 539
• To prepare a configuration script for Alteon 2, page 540
• To synchronize Layer 4 parameters from Alteon 1 to Alteon 2, page 542
To configure Layer 2 and Layer 3 parameters on Alteon 1
This procedure assumes you have already configured SLB parameters.
1. On Alteon 1, configure the external ports into their respective VLANs as shown in
Hot Standby Configuration, page
>> Main# cfg/port 3/tag ena
>> Main# /cfg/l2/vlan 172
>> VLAN 172# ena
>> VLAN 172# name ISL_and_servers
>> VLAN 172# add 3
>> VLAN 172# add 4
>> Main# /cfg/l2/vlan 192
>> VLAN 192# ena
>> VLAN 192# name clients
>> VLAN 192# add 15
>> VLAN 192# add 16
2. Trunk the ports you configured for the client VLAN.
>> Main # /cfg/l2/trunk 1
>> Trunk group 1# ena
>> Trunk group 1# add 15 16

(Add the external ports to the
trunk)
