Hi Experts,

I have to gateway routers that are connected with 3560 switches. R1 with SW1
and R2 with SW2 and then both switches are connected with each other.

R1 R3
| |
SW1 ----------- SW2
R1 F0/0 10.1.1.1
R2 F0/0 10.1.1.2
Sw1 vlan10 10.1.1.3
SW2 vlan10 10.1.1.4
R1 and R2 are connected with provider via bgp and connected with switches via
EIGRP. Switches interfaces that are connected with routers are in same vlan
10. R1 and R2 are advertising default route with same cost so both switches
have default route with two equal cost next hop. Switches are running HSRP for
internal users.

Now traffic coming from inside network is for same destination (that is a
proxy server on internet). And the problem is, HSRP active switch send all
traffic to one router and not loadbalancing on both routes (may be because
destination is same). My requirement is even traffic is for same destination,
it should be loadbalance between both links.

One solution is i replace HSRP with GLBP or HSRP with multiple groups but this
change is not possible for me.

Waiting for Solution
