Hi guys,
I have my two Cisco L3 switches connected via a L2 link on which I activated EIGRP 10 and the neighborship is up.
vlan 50 : 172.17.192.128/25 --------[L3_SW_2] Fa0/24====L2====Fa1/0/48 [L3_SW_1] -------- vlan 50 : 172.17.192.0/25
The interco subnet of the L2 link is : 192.168.1.200/30
From L3_SW_2, I am able to ping an IP of the vlan 50 behind L3_SW_L1 : 172.17.192.24.
But the reverse doesn't work (I tried to ping from L3_SW_2 an IP behind SW_1 : 172.17.192.130 which desn't work).
L3_SW_2#sh ip route eigr

Gateway of last resort is 172.17.192.210 to network 0.0.0.0
172.17.0.0/16 is variably subnetted, 3 subnets, 2 masks

I need your help on this. Please ask me if you need other command outputs.
Thank you,
