pbr

[Robo123]

Can any one clarify PBR with out set command how it will cause high cpu,

is it will create ARP packets.

[Georg Pauwen]

Hello,

PBR in what context/configuration ?

[Richard Burts]

I agree with Georg that more information about context and configuration would be helpful. But I have a fundamental question about this question. It asks about pbr without a set statement. The purpose of pbr is to provide an alternative to the route for that destination in the routing table. Without a set statement how can that happen?

A route map with no set statement is quite possible. For example a route map used to control route redistribution may very likely have match statements to identify certain routes to be redistributed without hsving a set statement (which could set a metric or a tag or some piece of routing information). But how can you achieve pbr without a set statement?

Hi George,

Let me brief out the issue.

Below is the config.

route-map VFL_Traffic permit 20

!

route-map permit-all deny 1
match ip address proxy_ip

!

route-map permit-res deny 6
match ip address prefix-list VGL_N

Is the above config will cause high cpu?

How PBR will create ARP packets which will cause CPU high?

[Richard Burts]

You have shown us two route maps but you have not shown us how they are applied and you have not shown us the acl used in each route map. These things might have impact on cpu. But seeing the route maps reinforces my opinion that they will not successfully implement pbr.

Hi Richard,

Let me summaries.

i have created  2 policy in my router.

route-map VPL_Traffic permit 10
match ip address VPL
set ip next-hop <ip address>
!
route-map VPL_Traffic permit 20
!

same policy am calling in interface GigabitEthernet1/9.

interface GigabitEthernet1/9
description BSNL  P2P Link 
bandwidth 10240
ip address <-------------->
ip flow ingress
ip flow egress
ip policy route-map VPL_Traffic
ip ospf network point-to-point
ip ospf cost 100
load-interval 30
speed 100
duplex full

Is this "route-map VPL_Traffic permit 20" policy conf with out set command will create High cpu or not?

please clarify the above...

[Richard Burts]

route-map VPL_Traffic permit 20

This statement in the route map has no match statement and no set statement. It will not do anything and it will not create high cpu. It is not needed and you can remove it from the route map. There are some usages of route map where you might need a statement without a set statement (and perhaps without a match statement) such as route map to control redistribution of routes. But for pnr there is no need for a statement without a set.
