Adding access points to 877W ISR

I have a customer who has an existing 877W on his network. He wants to add an access point in another area that is not covered by the ISR's wireless capability. Can the access point be plugged into the ISR and connect into the existing vlan's/ssid's or is it not possible because there are no layer 3 ports? He has the same scenario at another site but here he is using an 1801W. Any advice or links to configs etc much appreciated.


Re: Adding access points to 877W ISR

He wants to plug an AP directly into the router? That's fine to do as long as you configure subinterfaces on your FastEthernet interface for trunking.

Does his router have a switch connecting to it? If so it would make more sense to plug the AP into the switch.

Example config:

int fa0/0

no ip address

int fa0/0.1

encapsulation dot1q 1 native

ip address x.x.x.x m.m.m.m

int fa0/0.2

encapsulation dot1q 2

ip address x.x.x.x m.m.m.m

int fa0/0.3

encapsulation dot1q 3

ip address x.x.x.x m.m.m.m

int fa0/0.4

encapsulation dot1q 4

ip address x.x.x.x m.m.m.m

Something like that.

Re: Adding access points to 877W ISR

I think you misunderstand possibly Jeff. The ports on the 877 are layer 2 so you cannot use subinterfaces. Its a question really of trunking between the AP and the 877 without actually having a layer 3 interface.
