Ping drop and latency problem occurs when I apply PBR

[abhijeet.acs]

Hi

I have 2 internet connections and I have seprate address pools for these connections. I applied PBR on each interface of switch to route the data based on source ip pool.

When I apply this PBR on interface suddenly latency increses from 2ms to 55ms and sometime echo packets were dropped.

Pool 1 : 101.1.62.0/24

GW: 125.56.2.1

Pool 2 : 202.1.1.0/24

GW: 182.78.9.1

access-list 1 permit 101.0.62.0 0.0.0.255

route-map filter permit 10

match ip address 1

set ip next-hop 125.56.2.1

route-map filter permit 20

set ip next-hop 182.78.9.1

int f0/1

ip polcy route-map filter

Hello

Basically at present any traffic that isn't soured from acl1 will be sent to 182.78.9.1-  is this what you desire?

Where does this 101.0.62.0 0.0.0.255 network reside?

Also you have no resiliency set in place, so if the next hop interfaces are unreachable your present policy will still try to forward traffic based on the match statements and start arping for the next hop address.

apply set ip next-hp verify-availability to the policy so in this way the router will do a cdp lookup for the next-hop address before policy routing and if not found will instead route normal.

access-list 101 permit icmp101.0.62.0 0.0.0.255  any

access-list 101 permit icmp any 101.0.62.0 0.0.0.255

debug ip policy

debug ip packet 101 detail

Hi,

Yes any traffic that dosent sourced from acl1 will be sent to 182.78.9.1.

set ip next-hop verify-availability

I entered this command still there is latency problem.
