check that the setup is working by pinging each of the ip addresses,
both should work.

if you're using Apache as the http server, then look at the documentation
for virtual hosting.  you only need address virtual hosting which is perhaps
easier than name virtual hosting where you have to port 80 servers on the
same ip address.   there's probably an example at the bottom of the
httpd.conf file on your machine.   your entry will need to look something
like this:

DocumentRoot /export/www/mentor
ServerName sonomamentoring.org
ServerAlias www.sonomamentoring.org  sonomamentoring.org
ServerAdmin jwittes at thegrid.net
ScriptAlias /cgi-bin/ /export/www/mentor-cgi/
ErrorLog /export/www/mentor/logs/error_log
CustomLog /export/www/mentor/logs/access_log combined

put your the eri0:1 ip address on the VirtualHost line.  if you don't have
a separate cgi directory, then you can leave the ScriptAlias.   if you
don't want a separate log files for the two ip addresses, then leave out
the two log lines.   eri0 will be served by the default config choices
earlier in the httpd.conf file.

i get the digest version.  sorry if someone has already answered.
