Solved: Route Map Policy on SVI - Trunk from ESX

Gregor Blaj · ‎07-08-2014

Hi,

I have a question regarding the following configuration.

A route map matches traffic from a particular subnet, say on VLAN 10 (using an ACL).
A route map policy is applied on this SVI (int vlan 10)
A server on this subnet is running on ESX which is connected to the switch on a trunk port.
The ESX host tags all frames from this server as VLAN 10.

In this scenario, should the route map pick up the traffic from this server? I don't see why not, but in my testing it doesn't seem to be working :)

Thanks for any help.

Hi,

What kind of switch and IOS version are you running.

Just a pointer if you are using a 3750 you should
change the SDM template to:-

!
sdm prefer routing
!

then configure your acces list, route maps etc

Hi Alex,

It's a 3750x (stack) with 12.2(55)SE5.

I've already changed the SDM template to routing and rebooted the switch.

I don't think the route map is working at all actually :) See config below, let me know if you can spot anything obvious but the networks on the ACL are definitely correct.

Thanks again.

Extended IP access list UPLINK2
10 permit ip 192.168.1.0 0.0.0.255 any
20 permit ip 192.168.4.0 0.0.1.255 any (305 matches)

route-map ROUTE1 permit 10
match ip address UPLINK2
set ip next-hop 10.1.1.253
!

interface Vlan10
ip address 192.168.5.254 255.255.254.0
ip policy route-map ROUTE1
end

Hi Paul,

Wouldn't that only affect the traffic coming from the switch/router itself?

Cheers

Turns out you have to re-create the route-map after changing the SDM template to routing. Even though this is not documented it's what worked.

Thanks for the help everyone.
