In order for the IBM® WebSphere® SIP proxy server
to correctly interoperate with the IP routing load balancer, configure
the SIP proxy server to accept and handle all incoming packets from
the IP routing load balancer device, and to expect OPTIONS messages
from the IP routing load balancer.
Procedure
- On the WebSphere SIP
proxy server, log in to the Integrated Solutions Console as the WebSphere administrator.
- From the Sametime® System
Console, click .
- From the list of WebSphere proxy
servers, select the WebSphere proxy
server you are configuring.
- On the Configuration page, in the Proxy Settings section,
expand SIP Proxy Server Settings, and then
click SIP proxy settings.
- In the Load balancer health checking section,
in the Load balancer members IP address 1 field,
type the physical IP address of the load balancer that sources the
SIP health checks. This is the self-ip address of the IP routing load
balancer. The load balancer that does the health checkeing is also
referred to as a service advisor.
- if there is more than one load balancer, in the Load
balancer members IP address 2 field, enter the IP address
of the second load balancer.
- In the SIP health check method name field,
type OPTIONS. click OK.
In step 5, IP address 1 represents the
self-ip address of the IP routing load balancer. The IP routing load
balancer self-ip is configured during IP routing load balancer network
setup. In step 6, OPTIONS is specified as the SIP health check method
name. Based on this configuration, this SIP proxy server accepts all
OPTIONS messages that have a source address identical to IP address
1, and replies to them with a standard 200 OK response.
- Click OK to save the SIP proxy server
settings.
- Save the change to the master configuration by clicking
the Save link in the "Messages" box at the
beginning of the page.
- Repeat this procedure for every WebSphere proxy server in the cluster.
