Asymmetric routing query

[ajay kondapalli]

                  We have  2  Router A and B which are connected to single ISP with EBGP configuration.

and in my Lan there are two vlans one is vlan 10 and vlan 20 .vlan 10's traffic is going via Router A and vlan 20's traffic is going via Router B

but the problem is , the return traffic of vlan 10 coming via Router B and the returning traffic of vlan 20 is coming via Router A  which is not expected !

vlan 10 traffic should go and return on the same path which is router A and should happen same for the vlan 20. why such kind of Asymmetric routing occurs  and how can we solve this problem

and please post any related documents.

Thanks,

       Ajay

Hi,

Network topology  diagram will be helpful. And BGP configuration of both routers. What kind of routers are they?

It hard to understand without those information.

Hope it will help.
