[c-nsp] HWIC-4ESW and Pseudo-WIRE L2TPV3

[Jean-Dominique BAYLAC]

Hello all.

I try to realize a setup with 2 cisco 2801 to backup a fiber in case of 
outage.
We have 2 pairs of cisco 3750 on each site with one path to fiber, and 
one path via pseudowire

On 2801

interface FastEthernet0/0
  ip address 10.0.0.1 255.255.255.252
  speed 100
  full-duplex
  no mop enabled
!
interface FastEthernet0/1
  no ip address
  duplex auto
  speed auto
  no cdp enable
  xconnect 10.0.0.2 1 encapsulation l2tpv3 pw-class BACKUPLINK


I need to interconnect the 2801's to a third site. This time is a 
classic vpn with route.

HQ: 192.168.0/24
REMOTE: 192.168.10.0/24


But with my current setup, 2801's pass the trafic of the 3750's but, 
don't care the content of packet.

i need to connect another interface from the 2801 to the 3750,


I want to know if is possible to xconnect a port from HWIC-4ESW, or i 
need absolutly HWIC-1FE(L3 port) ?

Thank's for your reply
