I`ve configured l2tpv3, vlan xconnect tunnel between 2 7200 routers (for vlan 990). By checking session details, seems like tunnel is up and everything is working ok.
Both routers (on their sides) are via port channel connected to 4500 switches. Vlans (990) are created on each switch, and allowed on portchannel trunk port to routers.
Problem is that ping from host (vlan 990) on first switch cannot reach host on second switch (vlan990).
This is production network, but when this scenario was tested in lab, everything worked fine!
Only difference is that in lab configuration, port channels intefaces was not used (switch and rtr has been connected via simple trunk int.).
So, are there any restrictions with l2tp and portchannel, or where could be problem? any suggestion welcome :)
