Example 2: Layer 3 Server Cluster
In this example, A server cluster is configured with a unique IP address and a static ARP entry (cluster
MAC) and a port list. Here, the server cluster IP address must be a unicast address.
Switch connected to an L3 server cluster through 3 ports (1/3,1/4,1/5)
•
The traffic which ingresses on 1/1 or 1/2 destined to the server cluster IP is routed to all the egress
ports configured (1/3,1/4,1/5). The ingress ports are on a different VLAN as the server cluster IP inter-
face.
•
However, all the egress ports need to be in the same VLAN as the IP interface of server cluster. The
other traffic must be switched according to the normal switching/routing logic.
•
Egress port can be a linkagg port as well.
Configuration Example
In this example, a packet is an L3 or IP switched packet.
1
Create a server cluster that will become the HA VLAN by using the command
and
configure the mode. For example:
-> server-cluster 2 mode L3
2
Create a default VLAN for the HA VLAN ports with the
command as shown below:
-> vlan 12
3
Assign member ports to the new default VLAN with the
command as shown
below:
