Chenyan,
My first thought is why would you have this secondary address
configuration requirement. The second line which says "interface vlan8"
tells me this is a
catalyst 4000, 5000, 5500, or 6500 switch with a RSM, RSFC, or MSFC. Now
this begs the question why would you ever need to configure a second
address. I would have to say if this happens then someone didn't do their
job. This simply would not make any sense, why? Because it would be easier
to designate a port in a separate vlan and the create a matching layer three
interface for the segment. In any case I did not think this would work but
I found this link on CCO with no other references as to how this would be
implemented.
http://www.cisco.com/univercd/cc/td/doc/cisintwk/ics/cs009.htm#xtocid122336
"Cisco IOS Software Releases 10.2(9), 10.3(6), and 11.0(2) allow standby IP
addresses to respond to ping requests. Cisco Software Release 11.0(3)(1)
provides improved support for the use of secondary IP addresses with HSRP".
Now, in thinking about this I see the possibilities with MHSRP. Does anyone
have a working environment or tested this in a lab. You would need an AGS+,
3600, RSMs, AS5800 or the 7000 model routers.
Further searching of CCO yielded this result..
http://www.cisco.com/warp/public/cc/pd/iosw/iore/prodlit/768_pb.htm Well
sure enough here is a good configuration example. Of course as I noted
using a router I could see using this configuration, however in a switched
network it would not make any sense.
