PBR policy rejected

Junior Mateus
Level 1
Level 1

Hello Everbody

I have 2 router ( setting as HSRP Standby )

My lan point to the defaut gateway of the standby address ( 10.30.21.6)

On the Router 1 (high priority standby ) i have configured on the lan interface a PBR that redirect traffic http/https  from ip 10.30.104.0/24  from my lan to the next hop of 10.30.21.4 (R2)

I have to mention that R1 and R2 are on the same segement

here is the detail configuration

R1

As YOU CAN see Nothing working  on the route-map and the PBR

I don´t know what happen ?

The core switch is a better place for PBR since you can do better manipulation there. You can set up an SLA to verify the 2nd router is up and send the traffic there if it is. If its down, it can route as normal.

My first question would be where is 10.30.104? That does not match the subnet of the interface that you show us. So what interface does it connect to?

hello, thank you for your question,

The 10.30.104.X is on vlan of my CORE SWITCH

and my CORESW have a default route  to the HSRP Standby address ( 10.30.21.6)

i have one vlan 21 on my CORW that have this address 10.30.21.2/29 and this interface are directly connected to the interface inside of the R1 ( 10.30.21.1/29)

interface Vlan21

description RESERVED-HSRP

ip address 10.30.21.2 255.255.255.248

interface GigabitEthernet2/17

description connected to Router 1

switchport

switchport access vlan 21

switchport mode access

spanning-tree portfast edge

ip route 0.0.0.0 0.0.0.0 10.30.21.6 250 name  virtual_HSRP

The Router 1 and 2 Process NAT the for internet


Thanks for the information. One thing I had wondered about was whether the PBR was configured on the right interface. It must be configured on the interface where the traffic arrives. And since the source address specified in the ACL did not match the subnet where PBR is configured I wondered if there was a mismatch. But your explanation clarifies that it is on the right interface. So I begin to wonder if the suggestion from Robert is something that we should check. Can you change the route map and specify a next hop that is not the other router - preferably a next hop is some other subnet. I know that it would not produce the result that you want but it would at least give you a chance to run the debug and see if PBR was not working because of the choice of next hop.

Hello , thanks, i have mouve the PBR to the Coresw now it working, thank all for your help !

It looks like you're trying to redirect the matched traffic back out the same interface it entered on so it can travel to the other router. Is that correct?

I'm not sure if that type of redirection is supported with PBR.
