New VLAN subnet pointing reverse route in router

[#1]

Hi,

I have a cisco 1841 router and Switch Jnuiper ex2200-24T. I have created new vlan for set of users and advertised that subnet in bgp. Please let me know how to pointing the reverse route of new VLAN subnet in router pointing to switch.

I am assuming that the question is how would the advertising router or the edge router would know to reach the new vlan:

- first of all if the router that's advertising this new vlan (prefix) into BGP won't be able to do so if it doesn't have route installed in its RIB either by static or some dynamic routing protocol (IGP).

- You can check if you have the route for new vlan from the router:

show ip cef 192.168.1.0 (replace it with the right network address)

or you can simply try pinging it.

- I may have totally missed the question, if so please me know. Sharing configuration of router and switch will help.

Let me explain the exact scenario what has been done.

I have created one new subnet which has 10.70.1.0/24 in switch for Wireless in my branch location. Same subnet has been advertised in bgp in Cisco router to access applications which is hosted in my Data centre.

Is there reverse route required for Wireless users who is access applications from my branch location ? If so where need to configure and let me know the command for reverse route.
