Level 1

My 3750x with IP base license, and eigrp configured, does not push it's routing table to the hub router.  the 3750x however, recieves an udated routing table from the hub router.

System image file is "flash:/c3750e-universalk9-mz.122-58.SE1/c3750e-universalk9-mz.122-58.SE1.bin"

eigrp stub summary

switch is connected to a 2921 router on a L3 interface, ("no switchport" on interface).

EIGRP is conifgured. 

The 3750x recieves the dynamic routing table from the 2921.

The 2921 does not get the routing table from 3750x.

3750X running ipbase license only allow EIGRP stub.

In your config, you have configured eigrp stub summary. This command means EIGRP will only advertise summary routes. Please see the follow link for explaining of the eigrp stub command:

Hi jeye,

will francisq solution works if he replace 2921 with 3750x? although 3750x IP base only has eigrp stub will both 3750x switches recieves the dynamic routing table?

Hi

When you are using the 3750X with ipbase,then it can only be used as a Spoke router not as a hub.

Since EIGRP stub cannot acts as transit ,it only act as edge.

Also the command:

eigrp stub summary,the routes will be summarised,which i think is not desired in your case.

If you use eigrp stub connected or eigrp stub static then the stub router will send the connected and static routes respectively to the hub router.

eigrp stub connected static can also be used.

Also it will be better that you use no auto-summary while configuring EIGRP.

Hope that helps.

Thanks Girish

if i have R1 <--> R2  , R1 <--> R3, R3 <--> R2 , all 3750-x with IPBase, is eigrp stub sufficient enough to achieve redundancy in case if there is link failure between R1 and R2?

eigrp stub summary

Hello, francisg. You have to configure summary on interface like this way

int gi 1/0/48

ip summary eigrp 100 10.x.x.x 255.0.0.0

Other option is configuring

router eigrp 100

eigrp stub connected summary
