Hi All,
I am having a problem with my local policy routing and can not figure
out why it is not working:
Topology:
=======
R3, R4 and R6 forms a triangle
Networks:
=======
Between R3, R4: 142.1.34.0/24
Between R3, R6: 204.12.1.0/24
Between R4, R6: 142.1.46.0/24
R4 also have IP address 142.1.0.4
OSPF is configured in a way that ping from R6 to 142.1.0.4 would go thru
R3 first (R3 touches area 0)
I am trying to use policy routing to route ICMP from R6 directly over
the connection between R4 and R6 which is not in OSPF
Configuration
=======
R6:
router ospf 1
log-adjacency-changes
network 54.1.3.6 0.0.0.0 area 3
network 204.12.1.6 0.0.0.0 area 3
ip local policy route-map PING
!
ip prefix-list 10 seq 5 permit 142.1.0.0/24
!
!
route-map PING permit 10
match ip address prefix-list 10
set ip next-hop 142.1.46.4
Result
=====
R6(config)#do trace 142.1.0.4
Type escape sequence to abort.
Tracing the route to 142.1.0.4
1 204.12.1.3 0 msec 0 msec 4 msec
2 142.1.0.4 28 msec * 28 msec
R6(config)#
R6#sh ip loc pol
Local policy routing is enabled, using route map PING
route-map PING, permit, sequence 10
Match clauses:
ip address prefix-lists: 10
Set clauses:
ip next-hop 142.1.46.4
Policy routing matches: 5 packets, 320 bytes
Which means R6 still go thru R3 first before getting to R4!! Also, the
packet count in "sh ip loc pol" does not increase
Am I missing something obvious? How do I debug further?
Thanks a bunch!!
