Re: Connecting through BGP

Hi

Do you use Bgp on your router ?

Do you use the same router to connevt to your 2 isp ?

Regards.

Re: Connecting through BGP

Hello Manzoor,

even with static routes you could achieve this...

using floating static:

ip route 0.0.0.0 0.0.0.0 x.x.x.1

ip route 0.0.0.0 0.0.0.0 x.x.x.2 240

If you loose route to x.x.x.1, you'll start to use route through x.x.x.2.

HTH,

if it does, please rate this post.

Hi Vladimir,

It 'll not work if the wan interface is Broadcast multiaddress like (ethernet , or token etc...).

You can use rtr:

we need more information to give you the more adaptable solution.

Re: Connecting through BGP

Hello,

float static is only helpfull on serial links, yes.

a better link would be:

http://www.bgpbook.com/archpolicyexitdestindep.html

"How Can Floating Static Routes Fail?

The key to understanding the limitations of floating static routes is knowing how an interface is marked as "down." The details vary depending on the media used, but in general, an interface is considered down when signaling at the link layer is lost."

Anyway its a good example for other cases,

Vlad
