local subnet not able to see remote networks passed 3850

tcrane8080

Level 1
i just installed a 3850 and my local site is not able to see any networks passed the 3850.
i believe EIGRP STUB CONNECTED SUMMARY command is causing this.
 
any thoughts?

Thanks!

Bit difficult to say without more details.

Jon

Jon, i'll attach a "sh run" for ya.

the putty output is from the 3850

Do the upstream devices have routes for those local subnets ie. I notice you have a default route on the 3850 pointing to an upstream device.

Jon

let me check the 3850's default route.

yeah, with EIGRP running the local LAN should know about the 3850's network and the networks passed it.

i have another site with basically the same topo that i haven't touched and it's running fine.

so, i've screwed something up when i added the 3850

I notice you also have another default route pointing to 10.30.31.254.

Whatever that device is you are not running EIGRP with it are you ?

Jon

i have a 1841 connected to the SW for the backup link.  Since the SW doesn't have a serial port i have the RTR connecting to a cradlepoint.  which, when the main connection, 10.30.13.9 goes down the traffic goes out the RTR and thru the cradlepoint

Can you post a "sh ip eigrp neighbor detail" from both the 3850 and the upstream device ie. the main default route device.

Just to clarify you have checked the upstream device and it has routes back to the 3850 local subnets ?

Jon

below is the L3 switch that connects to the 3850:

KWCHSW15#sh ip route 10.30.31.0

the int 24 on the 3850:

interface GigabitEthernet1/0/24
 description NetVX Connection to KWCH
 no switchport
 ip address 10.30.13.10 255.255.255.252

 

and, please ask away!  

What happens if you just configure the 3850 as normal EIGRP ?

Jon

Jon, sorry for the delay!!

what i found was the new 3850's come from the factory with a "universal" IOS and

what determines which services are these lines when you do sh ver:

License Level: Ipservices
License Type: Permanent
Next reload license Level: Ipservices

 

once i ran license right-to-use activate ipservices all acceptEULA

IPservices was enabled.

 

Thanks for your asistance!!
