Hi Arup,

With this configuration, any packet that is coming into the switch from the 20.20.20.0/24 subnet (vlan2), will be sent out to next hop 30.30.30.2 through interface vlan3.

Is this what you want?

just i want vlan 2 will admin vlan which will access all vlan .how i can do it

Istvan_Rabai · ‎10-21-2008

Hi Arup,

From interface vlan2 remove the "ip policy route-map" command.

This way vlan2 will access all other vlans within this switch, supposed ip routing is enabled.

Cheers:

Hi Arul,

Please remove "ip policy route-map" from vlan2.

The commands for this are

conf t

interface vlan2

no ip policy route-map pbr

Also, please enable ip routing:

conf t

ip routing

This document provides the configuration and troubleshooting steps applicable to the creation of Layer 3 interfaces. VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing. On Catalyst switches it is accomplished by the creation of Layer 3 interfaces (switch virtual interfaces (SVIs) ).
