I am trying to use policy Base routing to move traffic.
- From Subnet A to C through R1-R2-R3-R4-R5-R6
- From Subnet B to C through R1-R2-R5-R6
- All path have equal cost
- I need to track the subnet between R3 and R4 for failure, incase of failure I need to redirect traffic using the
Routing protocol.
- The policy base routing will need to happend at R2.
Has anyone used next-hop recursive? Any issues to watch for? I want to make sure that a black hole is not created.
I am thinking of using PBR this way and apply it to the incoming traffic on R2's s0:
-----------------------------
route-map Test permit 10
match ip address 101 ! Defines the match criteria for subnetA.
set ip next-hop recursive {IP of R3's s/0} ! If the match criteria is met, the recursive IP
address is set.
------------------------------
SubnetA| |SubnetB

e0| |e1

| R7 |------------| R1 |
---- ----
| |
| |
| S0|
---- ----
| R3 | -----------| R2 |
