Hi all

we have two point2point link as a media between our side and another customer side. isp one - 4mbps link and isp2 - 100mbps link

in our side configuration :-

int gi0/1

ip add 192.168.111.205

descr one isp

int gi0/2

ip add 192.168.111.210

descr second isp

 

ip route 10.68.10.0/24 192.168.111.206

iproute 10.6810.0/24 192.168.111.211 metric 150

 

customer side configuration:-

int gi0/1

desc isp1

int gi0/2

desc isp2

vlan 1

10.68.151.163/24

ip default-gateway 10.68.151.1

 

so my question that "when i shut one interface of isp1 and then check point2point  bandwith then it give around 90 mbps. and when i no shut of isp1 then it give 2 mbps bandwith"

 

I want to runn parellel both of link with failover and give bandwith rightly..

plz suggest me

You are sending traffic via ISP1 link which is only 4Mbps. so when both links are UP, you see only limited traffic. Also your ISP2 link is standby so it will not carry any outgoing traffi untill ISP1 is down.

See the output of "sh int gi0/1" I suspect there will be huge drops. So when you shut ISP1 (4Mbps) link, then all traffic start flowing via ISP2 which is 100Mbps and you see arround 90Mbps traffic.

If you want to run both links in active/active, then need to use EIGRP.

 

Ok I checked that if we remove one route 192.168.111.206 in our side nd in this hve only one route 192.168.111.211 then it will also show around 2mbps bandwith.when I shut isp1 on the customer side switch then it show correctly

So my question is that why this happened. And what should I do?  any configuration then plz provide any link.

can u share the output of below from customer switch:

"sh ip route" when both links are up from both side

"sh ip route" when ISP1 is down from ur end but up at customer end

 

I checked nd notice tht when I trace route from our side switch then it will go isp2 nd trace cmplte  dst at cstmr side switch . Or when we trace from cstmr side switch. Then it will stk on isp1 interface ip and trace not complte so I think some of misconfiguration or any othr happend at cstmr side switch.  plz tke Care of this why this stk and when at cstmr sideb switch isp1 prt sht then it will trce cmplte on both of side
