How to do L2TPV3 on 6504 with 15.1SY and Sup720

[David Fitzgerald]

I'm attempting to pass some L2 traffic through a L3 tunnel, but the means I would normally use does not seem to be implemented.

This would normally look like:

• On each of the routers, Router 1 with loopback 10.83.251.254, and Router 2 with loopback 10.29.254.241.  Routers 1 and 2 have multiple L3 paths between them utilizing EIGRP.

conf t

ip cef

l2tp-class DMZclass

authentication

password DMZ_l2tpv3

• On each of the routers

conf t

pseudowire-class PW_DMZ

encapsulation l2tpv3

protocol l2tpv3 DMZclass

ip local interface Loopback100

• On Router 1:

interface Gi2/9

xconnect 10.29.254.241 1 encapsulation l2tpv3 ps-class PW_DMZ

• On Router 2

interface Gi2/9

xconnect 10.83.241.254 1 encapsulation l2tpv3 ps-class PW_DMZ

I'm curious as to why this isn't implemented. I thought it was implemented in 12.4 (which is not available for my 6504 with Sup720).

What alternatives exist for accomplishing the same result?
