Question about prefix list

2012-02-01 Thread Ann Kwok
Hi

I read this prefix list.

Can I know why there is "le 24" after network block in /22 and /21

Why don't have "le 24" after /24?

I also saw another prefix list before. They use "le 32" instead of  "le 24"

What are their different?

ip prefix-list prefix-filter-as100 seq 10 permit 202,168.136.0/22 le 24
ip prefix-list prefix-filter-as100 seq 20 permit 202,22.92.0/22 le 24
ip prefix-list prefix-filter-as100 seq 30 permit 202,21.148.0/22 le 24
ip prefix-list prefix-filter-as100 seq 40 permit 203,178.88.0/21 le 24
ip prefix-list prefix-filter-as100 seq 50 permit 178.88.74.0/24

Thank you so much


Switch and router

2012-02-06 Thread Ann Kwok
Hello

There is big congestion between router and switch

I read some documents about flowcontral

Do I disable or adjust flowcontral at the same?

Can flowcontral solve the congestion issue?

How can I adjust flowcontral in cisco router and HP switch?

Thank you so much

Hello

Thank you for your help

But we can't increase the pipe as we are using 10G switch.

The congestion happens when the traffic is using 7G

Any idea?

In addition, how to determine the congestion happens in router or switch.

Thank you

Please help our simple bgp

2012-01-30 Thread Ann Kwok
Hello

Our router is running simple bgp. "one BGP router, two upstreams (each 100M
from ISP A and ISP B)
We are getting full feeds tables from them

We discover the routes is going to ISP A only even the bandwidth 100M is
full

Can we set the weight to change to ISP B to use ISP B as preference routes?

Can the following configuration work?
What suggest to this weight no. too?

 neighbor 1.2.3.4 description ISP B
 neighbor 1.2.3.4 remote-as 111
 neighbor 1.2.3.4 weight 2000

If this works, how is ISP B upstream connection is down?

Can it still be failover to ISP A automatically?

If it won't work, Do you have any suggestion?

Thank you for your help
