[c-nsp] eigrp over atom

[Ray Burkholder]

I'm having problems getting eigrp to talk over an mpls l2 link between two
cpe devices.

cpe -- 3550 -- 7206 -- 7206 -- 3560 -- cpe

cpe - 3550: access port on 3550
3550 - 7206: trunked port on vlan 100
7206 - 7206: mpls l2 xconnect 
7206 - 3560: trunked port on vlan 100
3560 - cpe: access port on 3560

I'm connecting two sites via pseudowires.  A configuration similar to the
following is on each 7206:

mpls export interval 5
mpls ldp loop-detection
mpls label protocol ldp

pseudowire-class ATOM-E
 encapsulation mpls
 interworking ethernet
!

interface FastEthernet4/0.100
 description MPLS ATOM Site 1
 encapsulation dot1Q 100
 xconnect x.x.x.x 100 pw-class ATOM-E
!

The link has been working fine and is working fine for regular udp and tcp
traffic.  The desire now is to run EIGRP over this link.  When configuring
each end for EIGRP with a /30 interface, hellos are getting dropped.  For
EIGRP, I believe hellos are multicast, which I think is the key issue.

The hellos appear to be dropped before reaching the other end. 

Is there additional configuration required to get eigrp hellos across the
link, or will it just not work, or is it supposed to 'just work'?
