L2TPv3 with Layer 3 Gateway

derek.nolan

Level 1

Hi All,

 

Currently I have 3 sites, site 1 (switch 1), site 2 (switch 2), and then a main site with internet connectivity (Core Switch).

Connectivity between all sites is over layer 3 point to point circuits.

 

All switches are 4500 models.

At one point I had a request to extend a layer 2 vlan across the two sites for an intercom to function, because the 4500's do not support l2tpv3 I added a Cisco 890 to each site with a very simple config:

 

R1:

pseudowire-class IC_L2
encapsulation l2tpv3
ip local interface GigabitEthernet8
!
!
!
interface GigabitEthernet8
ip address 10.131.112.1 255.255.255.0
no shutdown
duplex auto
speed auto
!
!
interface Vlan10
no ip address
xconnect 10.131.114.1 10 encapsulation l2tpv3 pw-class IC_L2
!

 

 

R2:

pseudowire-class IC_L2
encapsulation l2tpv3
ip local interface GigabitEthernet8
!
!
!
interface GigabitEthernet8
ip address 10.131.112.1 255.255.255.0
no shutdown
duplex auto
speed auto
!
!
interface Vlan10
no ip address
xconnect 10.131.114.1 10 encapsulation l2tpv3 pw-class IC_L2
!

 

 

Works very nicely and the two intercoms can reach each other. Now though I have the need to provide the intercoms with routed internet access but am wondering how i add a routed gateway to this setup... Any ideas?

Hello,

 

can you post the full configs of both R1 and R2 ?
