Route-map IP-policy config on 3560 switch

s.kanth
Level 1
Level 1

Hi ,

We would like to implement Router-map on the core switch(C3560 model) and map it to VLAN3 interface.

Here is the configuration :

-------------------------


access-list 10 permit 10.40.58.0 0.0.0.255
access-list 10 permit 100.101.0.0 0.0.255.255


router-map leak_BLAN permit 10
match ip address 10
set next-hop 10.40.56.60
route-map BLAN permit 20

------------------------

But where this router-map should be implemented, but unfortunately “ip policy “command is not supporting in interface level (VLAN 3).

Cisco 3560 switch is rouning on "c3560-ipbasek9-mz.122-50.SE5/c3560-ipbasek9-mz.122-50.SE5.bin"

Any assistance would greatly be appreciated.

Thks

Sri

Hi,

.

This is an example of output from the show sdm prefer  routing command entered on a switch:

#

Switch# show sdm prefer routing

#

"desktop routing" template:

#

 The selected template optimizes the resources in

#

 the switch to support this level of features for

#

 8 routed interfaces and 1024 VLANs.

#

#

  number of unicast mac addresses:             3K

#

  number of igmp groups + multicast routes:    1K

#

  number of unicast routes:                    11K

#

    number of directly connected hosts:        3K

#

    number of indirect routes:                 8K

#

  number of policy based routing aces:         512

#

  number of qos aces:                          512

#

  number of security aces:                     1K

#

The reason I ask is that there are  certain unsupported configurations which prohibit the configuration from  be applied.  However the route-map can still be applied in this case  but will throw an error in the process.  For example, the only issue  that I can find regarding PBR on 12.2(53)SE1 is as follows:-

(Catalyst 3750 or 3560 switches and Cisco

EtherSwitch service modules) A route map that has an ACL with a 
Differentiated Services Code Point (DSCP) clause cannot be applied to a
Layer 3 interface. The switch rejects this configuration and displays a
message that the route map is unsupported. There is no workaround.

May be u can do like this:

plz download this IOS 122-55.SE1 . This is a new release of cisco for  3560. in this software there is a support for route-map to interfac

Hi Srikanth,

2 things to check -

1) are you running IP services/Advanced service (eg. not IP Base). You need to be.-

2) if you are running the right feature set have you enabled the SDM routing template.

Hi Sandeep,

Running IP Base IOS

If it does not support "IP-policy", what could be better option to fulfil my requirement.

thks

Sri

Hi s.Kanth,

You have to change the IOS, order a  new IOS with IP services.

http://www.cisco.com/en/US/docs/switches/lan/catalyst3750x_3560x/software/release/15.0_1_se/release/notes/OL25302.html

just check and order.

Please rate if it helps.

I will check the alternative, thanks. is it called PBR? ..am I right ?

Yes PBR  ispolicy based routing.

Just check the advance/ipservices ios for 3650 switch.

If you are satisfied with answer then please marked as answered.

Please are if it helps.

Thanks Sandeep for spending time on my request :-).
