Routing issue. Please help me

[JustTakeTheFirstStep]

The ASA does not seem to be doing ROUTING.

OA and FA are Track config of each other. But in FA, sla is down.

The IP 94 and 247 bands must be able to communicate with each other.

I attach the CONFIG_SCRIPT.

Do you know the cause ??

Please help me.

I did not find the cause.

I only believe you.

Hi,

[JustTakeTheFirstStep]

We should use Reduntdent.

I think there must be another reason.

Hello,

looking at your configurations, I cannot figure out what you are trying to accomplish with your IP SLA, and what you are actually tracking. I guess it would help if you could fill in the blanks below:

Incheon_OA_BB_1

Primary route to where (IP and device) ?

Secondary route to where (IP and device) ?

SLA ping to where (IP and device) ?

!

Incheon_OA_BB_2

Primary route to where (IP and device) ?

Secondary route to where (IP and device) ?

SLA ping to where (IP and device) ?

!

Incheon_FA_BB_1

Primary route to where (IP and device) ?

Secondary route to where (IP and device) ?

SLA ping to where (IP and device) ?

!

Incheon_FA_BB_2

Primary route to where (IP and device) ?

Secondary route to where (IP and device) ?

SLA ping to where (IP and device) ?

Hello,

the FA devices seem to be 3850 switches with IP routing enabled, what are the OA devices ?

[JustTakeTheFirstStep]

OA = C4507

[JustTakeTheFirstStep · Accepted solution]

I solved the problem.

I set ROUTING to 32BIT so that the TRACK state could be UP.

ip route 192.168.94.1 255.255.255.255 192.168.247.11

But I don't know if this is a normal solution.

Because OA does not have a problem with TRACK even if 32BIT ROUTING is not done.

Hello,

odd indeed. I could not find anywhere that the SLA needs a static host route. I also could not find any bugs. Either way, if it works that way, leave it as is, obviously...
