I need to connect an ASA5505 to a 881 using a Vlan

I am trying to connect two different networks together. The networks live simultaneously in a network closet, so I do not want to Connect then with a VPN.
Both networks have their own ISPs and should remain that way.
One network uses an ASA5505 base services model, and the other a Cisco 881.
I need to connect the two so that servers on either network can communicate.

I think it should be as simple as configuring an SVI on the 881 to the existing Vlan subnet on the ASA.

I am new at posting, and am planning to try this over the weekend. So I do not have configs yet. I am mainly trying to figure out if it is possible??

Hi  Jesse,

If I am in your position, what i will do is something like this:

First, if they are directly-connected, then

ASA5505[L3-interface]-------------------[L3-interface]Cisco881

or,

If they are connected via a L2 switch,

ASA5505[L3-interface]----------[L2}Switch[L2]---------[L3-interface]Cisco881

Configure one interface of the ASA and the interface of the 881 router with /30 point-to-point ip address.

Then static routes can be configured on both sides that is redistributed to routing protocols can be configured.

Example:

ASA5505:

configure terminal

interface Gx/y

description [To Cisco 881]

nameif

security-level

ip address

route ()

...

router ospf x

redistribute static subnets

or,

router eigrp x

redistribute static metric 1 1 1 1 1
