2960X - show ip route - shows unknown routes

Hi all,

I noticed on a 2060X which is connected to a vPC pair Nexus 5500 unknown routing entries. 

The displayed default gateway (.11) was present on one of the old Core Switches. While doing the migration the cisco Nexus acts now as the default gateway (.1) and and the old core switches were turned off. 

On the 2060X there is configured the default-gateway pointing to the HSRP address of the nexus. But there are on all 2060X some routes with another default gateway. 

ip default-gateway x.x.x.1

Maybe this is a bug ?! 

 

SWITCH-NAME#sh ip route
Default gateway is x.x.x.1

Host               Gateway           Last Use    Total Uses  Interface
a.b.c.d            x.x.x.11            0:05            7584          Vlan2
e.f.g.h            x.x.x.11             0:00            99681        Vlan2

 

.11 was the old gateway which was connected on the old core switches (other vendor)

 

Software on 2960X: 15.0(2)EX4

Thanks 

Udo

Hello Udo,Do you have a ip

Hello Udo,

Do you have         "ip route a.b.c.d 255.255.255.255 x.x.x.11 permanent"         in your 2960X config.

Hi Charles,

Hi Charles, No there are no static routes configured nor a dynamic routing protocol is running. It seems to be "no ip Host-routing " on 2960x and clear ip redirect on 2960S solved the Problem!! I don't know the reason!
