PBR: Can I apply policy/route-map to multiple interfaces on same layer 3 switch?

[Dean Romanelli]

Hi All,

I have a layer 3 core switch.  I am getting ready to set up WAN redundancy for my VOIP network and I want to use PBR. I will have my MPLS line be primary path to our VOIP provider, & my Internet line be backup path to our VOIP provider.  Problem is that I have 4 other switches in the access layer which IP phones are connected on and will need to get to the VOIP provider. These 4 switches run back to my distribution layer 3 core switch, where I have the PBR configured.

What I want to do is configure PBR, but I want to apply the policy/route-map on the 4 ports on my distribution layer 3 core switch that connect to my access layer 2 switches so that applicable traffic from those switches towards the VOIP provider will get PBR'd. 

Is it possible to apply the policy on more than 1 port on the device PBR is configured?

If I understand your distribution switch does the routing for vlans. If the ports on the distribution switch that your access switches connect are L2 then you don't apply the route map there, you apply it on the L3 SVI for the vlan(s) on the distribution switch.

If there are multiple SVIs then yes you can apply the same route map to them.

Perfect.  Sounds good.  Thanks Jon.
