Assigning Vrrp Virtual Router Id; Configuring Vrrp Peers For Synchronization - Radware Alteon Application Manual

Alteon Application Switch Operating System Application Guide
High Availability
Using VLANs to Eliminate Loops
When using VRRP, you can decrease failover response time by using VLANs instead of STP to
separate traffic into non-looping broadcast domains, as shown in Figure 87 - Using VLANs to Create
Non-Looping Topologies, page 569:
Figure 87: Using VLANs to Create Non-Looping Topologies
This topology allows STP to be disabled. On the Alteons, IP routing allows traffic to cross VLAN
boundaries. The servers use the Alteons as default gateways. For port failure, traffic is rerouted to
the alternate path within one health check interval (configurable between 1 and 60 seconds, with a
default of 2 seconds).

Assigning VRRP Virtual Router ID

During the software upgrade process, VRRP virtual router IDs is assigned if failover is enabled.
When configuring virtual routers at any point after upgrade, virtual router ID numbers (
using the
command) must be assigned. The virtual router ID may be configured
/cfg/l3/vrrp/vr #/vrid
as any number between 1 and 255.

Configuring VRRP Peers for Synchronization

The final step in configuring a high availability solution includes the addition of synchronization
options to simplify the manual configuration. Synchronization configuration options refine what is
synchronized, to what, and to disable synchronizing certain configurations. These options include
proxy IP addresses, Layer 4 port configuration, filter configuration, and virtual router priorities.
The peer menu ( ) enables you to configure the IP addresses of the Alteons
cfg/slb/sync/peer
that should be synchronized. This provides added synchronization validation but does not require
users to enter the IP address of the redundant Alteon for each synchronization.
Each VRRP-capable device is autonomous. Alteons in a virtual router need not be identically
configured. As a result, configurations cannot be synchronized.
You can synchronize a configuration from one VRRP-capable device to another using the
/oper/
command. All server load balancing, port configurations, filter configurations, and VRRP
slb/sync
parameters can be synchronized using this command.
Note: Before you synchronize the configuration between two Alteons, a peer must be configured on
each Alteon. Alteons that are synchronized must use the same administrator password.
