Hi ALL:
I am facing a strange issue
I have 2 router 1 for internet and other for MPLS
but what is happening for 1 ip address my traffic is going to the mpls router and then to the internet router
This is how the traffic is going for internet ip
1 <1 ms <1 ms <1 ms x.x.17.2
2 <1 ms <1 ms <1 ms c.c.c.6
3 <1 ms <1 ms <1 ms [z.z.z.1]----MPLS router
4 2 ms 3 ms 3 ms y.y.y.35-------Internet router ip
5 1 ms 1 ms 1 ms [x.x.x.70]
This is how it should go
1 <1 ms <1 ms <1 ms x.x.17.2
2 <1 ms <1 ms <1 ms c.c.c.6
4 2 ms 3 ms 3 ms y.y.y.35-------Internet router ip
5 1 ms 1 ms 1 ms [x.x.x.71]
Both ip in same subnet
On my L3 i have access port in 201 for internet and 203 for mpls even though the
L3A is connected to L2 with access port 201 vlan it sending 203 traffic i have no idea why?
I am running OSPf and have FWSM on both L3 which is connect to L2
This is the route on FWSM:
route outside x.x.x.64 255.255.255.240 10.206.206.35 1
both ip fall in this subnet .

Hi
do you have any specific policies applied in your L3 switch or in your FW to redirect the traffic to MPLS Routers ethernet ip ?
Is this the behavior for only one ip addrss ? what abt the rest of the ips are the going to without going to mpls router ?

You could also try applying a policy that denies traffic from going to the MPLS cloud. Sounds like you have a route leak.
Best practice I think is to tag the specific traffic and do a route-map deny statement to catch that traffic.

Hi Rock/Prem
The problem i with 1 specific ip only.
this is the route on the FWSM
route outside x.x.x.64 255.255.255.240 10.206.206.35 1
As i have said only 1 ip is taking the other path .
And if i put any ACL on the L2 switch for .70 ip than the traffic is dropping on the L2 itself
its not taking any other path.
and i am not able to understand how traffic for vlan 201 is going on 203 .
