Can PBR and route map work on IPBase image 3850 and Whether PBR is correctly configured by me ?

Hello experts,

Kindly suggest me the configuration change required or if wrong any.

Scenario: I want Wired users to go to HQ from MPLS line 1 and Wireless Users to go via MPLS line 2 and when one of them were not available it should fall back to available link.

Here is snippet :

Please find attached Image for scenario.

ip route 0.0.0.0 0.0.0.0 10.106.72.210
ip route 0.0.0.0 0.0.0.0 ????
!
track 50 ip sla 1 reachability
!
track 100 ip sla 2 reachability
!
ip access-list extended Wired_Users
permit ip 10.106.92.0 0.0.0.255 any log
ip access-list extended Wireless_Users
permit ip 10.106.93.0 0.0.0.255 any log

Hi Ranjan,

I think below URL can answer your query.

Hello

Looks like you can but need to change the SDM template

C3850

You can also trim your config down a little as you only will need to PBR on the Wireless users as they will not be using the default route

Also suggest to set the default route to a conditional default so when it connect is lost it will be removed for the rip and allow the secondary to be used.

Example:
ip route 0.0.0.0 0.0.0.0 10.106.72.209 track 1   <---this is your conditional default route
ip route 0.0.0.0 0.0.0.0 10.106.73.209 200     <---this is you secondary default with admin distance of 200

ip sla 1
icmp-echo 10.106.72.209 source-ip 10.106.72.210
frequency 5
ip sla schedule 1 life forever start-time now


ip sla 2
icmp-echo 10.106.73.209 source-ip 10.106.73.210
frequency 5
ip sla schedule 2 life forever start-time now

track 1 ip sla 1 reachability <----------For conditional route
track 100 ip sla 2 reachability <----------For PBR


ip access-list extended Wireless_Users
permit ip 10.106.93.0 0.0.0.255 any log

route-map PBR_Wireless_Users permit 10
match ip address Wireless_Users
set ip next-hop verify-availability 10.106.73.209 1 track 100

interface Vlan3
description "Wireless"
ip address 10.106.93.1 255.255.255.0
ip helper-address 10.106.75.21
ip policy route-map PBR_Wireless_Users
