Re: static route question ??
That's correct, and having a lower administrative distance means that a static route is "preferred" over a dynamic route, but not "faster." If the router has more than one way to get to a network in its routing table, it selects the path with the lowest administrative distance, which would be a static route by default. Sorry, if it seems like I'm being picky, but it sounded like maybe someone had told you the static route would be faster. It's probably just a language thing.

Re: static route question ??
Thanks for your reply Just want to clarify what I meant. When I said that static route gives us faster traffic transmission, it meant that static route's administrative distance is 1, which is lower than other dynamic routing protocols' administrative distance. Can I say this? Please correct me if I am wrong.

Re: static route question ??
Static routes does seem the best way to go in your situation. If it is a hub and spoke arrangment as i believe it to be in your case then static routes must be configured on the central router pointing to the networks on the remote locations and static routes must also be configured on the remote routers pointing to the networks on the central location. There is definitely a performance advantage using static routes in this case.

Re: static route question ??
Just being picky, but I can't see how static routing would give you faster traffic transmission than dynamic routing. The router still looks into the routing table and finds a route for the first process-switched packet. From then on it uses the fast-switching cache, (unless configured not to do so.) But just because it's a static route instead of a dynamic route doesn't make it any faster. Static routing uses less bandwidth because no routing updates are sent, but that's a different concern. Also, dynamic routing protocols can be slow to converge when problems occur, but fast-converging protocols such as EIGRP and OSPF wouldn't have this problem. Also, if you just have single links and no redundancy, there's nothing to converge to anyway. Static routes will work but could get cumbersome to configure and maintain as your network grows. Also, do the branch offices just need to get to the central office, or do the branches talk to each other? If so, a default route or a routing protocol might be a better option to avoid having to specify each network.

If there are no redundant links, then static routing will be faster. If there is a redundant link, Dynamic routing will give the benefit of fault tolerance.

Re: static route question ??
In a static topology, there's no need for a dynamic routing protocol. Only when the lack of flexibility and slow (manual) reconfiguration become issues do you need to think about routing protocols. For a simple, stable network, use static routes. -Gabriel McCall, CCDP/CCNP+Sec "jeongwoo park" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > HI all. > Situation: > There is a central site in San Francisco, and four > branches around Bay area. > Since static route gives us faster traffic > transmission, would it be the most desirable way to > configure static route on all routers, regardless > whether it is a central site router or branch office > router? > If not, why not? > > Thanks in adv. > > jeongwoo > > > __ > Do You Yahoo!? > Yahoo!

Re: Static route question !!
Yes, a route has to be added to each router. Additionally, any hosts that will be configured to send data accross the WAN will need there default gateway set to their closest router. Alternatively, you can use a routing protocol like RIP to have the routers "Discover" each other and create there own routes. Good Luck, E-mail with Questions.

Re: Static Route Question
Are they using a new IP address for the customer's Web site and e-mail server? If they are using the old IP addresses and they started with 204.90.95.0, they can't get there now since you removed the static route to that destination. It makes sense. This would be like removing the sidewalk to your house and then complaining that you can't get mail. &;-) Also keep in mind that Web servers and e-mail servers are actually accessed using Domain Name System names, which would have to be changed to map to the new IP addresses from the customer's new provider. DNS changes can take a long time to propagate around the Internet. The old information can get cached in a variety of places, including places that you have no control over.

Re: Static Route Question
No. The ISP is providing the T1 service. The customer went with another T1 provider, therefore the ISP wanted the static route for the customer removed from their router. But once this was done, they could not e-mail that customer or view their web site. The actual static route was: 204.90.95.0 255.255.255.0 157.130.119.113 The 204.90.95.0 address was the former customer's IP. The 157.130.119.113 is the IP of the ISP's backbone provider.
