Hi 

I am facing issue with Router secondary ip address of interface.

ROUTER<---VLAN1 ---->Core<------VLAN3---> L2_SWITCH----(VLAN3_PC)

 

interface GigabitEthernet0/0
 description ***** LAN_XXXL *****
 ip address 172.16.33.12 255.255.254.0 secondary    ( Local IP )
 ip address XXX.XXX.XXX.225 255.255.255.240       ( Public Ip )
 ip flow ingress
 ip nat inside
 ip virtual-reassembly in
 duplex auto
 speed auto 

 

Router has public ip as primary ip on LAN interface and it has secondary ip address of Vlan 1.

From core switch im able to ping router secondary ip but from VLAN 3 machine im not able to ping router secondary ip.

My ping tracert drops at core. 

 

In show ip route 172.16.32.0 /23 shows as connected route on both router and core switch.

ip nat inside source list 1 interface GigabitEthernet0/2 overload
ip route 0.0.0.0 0.0.0.0 xxx.xxx.xxx.193      ( public IP )
ip route 10.64.112.0 255.255.254.0 172.16.33.1
ip route 172.16.16.0 255.255.248.0 172.16.33.1
ip route 172.16.24.0 255.255.248.0 172.16.33.1
ip route 172.16.32.0 255.255.240.0 172.16.33.1
ip route 172.16.48.0 255.255.240.0 172.16.33.1

Hi Rajesh.

 

Please told me the IP address of the interface VLAN3, a "show ip router pc_address" in router and "sh ip route 172.16.33.12" in the Core Switch.
