We can't comment on performance unless we know the type and quantity of
traffic on your network and the how the rest of it is configured. What
speed are the links to your outlying routers and what is on the end of
them? Is there some kind of uplink from your central router and what is
its speed? What are the distances involved?

We decide to purchase bigger router (2800 series), make use of 2651 in
the other locate. Thanks you guides for all of the idea.

Thanks,

Whether that was indeed the case was the kind of information I was
fishing for initially. Since his (apparently obsolete) router has space
for more interfaces a second router may or may not be the appropriate
way to go. Depending on how his routers are connected and how his
network is monitored use of a dynamic routing protocol may be overkill.

Or just budget for it.

You need to have a think about where you are going. The simple option is to add
another 2651, and connect some links to that. That way if one fails, you only
lose part of your links.

You may want to ook at latger routers like a 3800 where you cen get a higher
port density, but just adding lots of ports to a single router increases the
hit should it fail.

You don't give us enough information, but based on that comment, I suspect yo
need to have a serious think.

It sounds like you have a single router. That is rarely a good thing as it is a
single point of failure.

You also don't tell us what the router is, and how you connect the sites in, or
how important these links are to the business.
