Solomon,
Locally generated traffic would have to be tagged using local
policy routing. Similar to my previous example, locally generated
traffic would be tagged as follows:
!
! Setting IP Precedence for locally generated traffic
!
access-list 100 permit tcp any any eq telnet
!
route-map IP_PRECEDENCE permit 10
match ip address 100
set ip precedence critical
!
route-map IP_PRECEDENCE permit 20
!
ip local policy route-map IP_PRECEDENCE
!
interface Serial0
ip address 1.0.0.1 255.255.255.252
random-detect
random-detect precedence 5 40 60 20
!
