Hi,
use a local PBR for ip sla ping packets which sets the df bit to zero.

I do that but it dosen't work , access list match trafic but the route-map match nothing.
route-map df, permit, sequence 10
Match clauses:
ip address (access-lists): 1
Set clauses:
ip df 1
Policy routing matches: 0 packets, 0 bytes
