Quick question about EIGRP and PBR on C3560

Redes Itconic
Level 1
Level 1

Hello.

We have 4 switches C3560 running EIGRP. We have PBR in one of them in this way:

interface FastEthernet0/22

no switchport

ip address 192.168.224.66 255.255.255.192

ip policy route-map wbcnvuemb16

load-interval 30

delay 50000

no snmp trap link-status

standby 214 ip 192.168.224.67

standby 214 priority 120

route-map wbcnvuemb16 permit 10

match ip address 55

set ip next-hop 192.168.1.6

access-list 55 permit 10.218.7.103

192.168.1.6 is reachable this way:

router1#show ip route 192.168.1.6

Routing entry for 192.168.1.0/29

  Known via "connected", distance 0, metric 0 (connected, via interface)

  Redistributing via eigrp 210

  Routing Descriptor Blocks:

  * directly connected, via FastEthernet0/23

      Route metric is 0, traffic share count is 1

We have conneceted a dedicated circuit in FastEthernet0/23.

The question is: ¿what would happen if circuit fails but FastEthernet0/23 remains in connected state?

192.168.1.6 will be unavailable.

PBR will maintain forwarding traffic to IP 192.168.1.6? This involve that this traffic will fail.

Regards.

Roberto.

Hello.

Thank you for the fast answer. I have read it and I also read this:

http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/54sg/configuration/guide/pbroute.html

http://www.cisco.com/en/US/products/ps6599/products_white_paper09186a00800a4409.shtml#wp14035

and

http://www.cisco.com/en/US/tech/tk364/technologies_configuration_example09186a0080211f5c.shtml#veri

There are some ways to verify availability but I need to know default behavior with the configuration that I attached.

Regards.

Roberto.

without tracking the next hop the policy routing config is only local significant, network failures do not automatically update the routing policy configuration. so if the curcuit fails, the next hop 192.168.1.6 will still be used to recursed on the routing table.

and traffic will be blackhole.
