Hi,
I need help regarding the PBR implementation. We have a layer 3 access switch with VLANS 2, 5, and 9 configured on it with SVI's (1.1.2.0/23, 1.1.5.0/23, and 1.1.9.0/23 respectively) and EIGRP enabled on it. I am attaching the config file of access switch for reference. This layer 3 switch is connected to Two core layer 3 switches (4506E). They are connected through 1) port channel 1 (1/0/50 and 3/0/50) on access switch to core 1 port channel 17 (3/17 and 3/18). 2) port channel 2 (1/0/52 and 3/0/52) on access switch to core 2 port channel 17 (3/17 and 3/18). I would like to implement the PBR on access switch telling all the subnets should pass through port channel 1 and portchannel 2. Below is the config I proposed, please let me know if this works fine if one of the port channels 1 of core 1 will get down. If not, I'll appreciate if any expert advice.
access-list 111 permit ip 1.1.2.0 0.0.1.255 any
access-list 222 permit ip 1.1.5.0 0.0.1.255 any
access-list 333 permit ip 1.1.9.0 0.0.1.255 any
!
route-map net-10 permit 10
match ip address 111
set interface Po1
!
route-map net-10 permit 20
match ip address 222
set interface Po1
!
route-map net-10 permit 30
match ip address 333
set interface Po1
!
route-map net-10 permit 40
!
int vlan 2
ip policy route-map net-10
!
int vlan 5
ip policy route-map net-10
!
int vlan 9
ip policy route-map net-10
!
But the problem here is if suppose Core 1, port channel-1 goes down then how this policy will route back to core-2 port channel 2. Will appreciate any help or expert advice on this .
Thanks
Ahmed
