I'm currently having an issue with loss of connectivy between the above mentioned router and switch.
After a few hours the directly connected interfaces are unable to ping each other and as a side effect we lose our eigrp adjacency. Only a reload of the sup8e switching to it's failover brings the links back. I have tried the same setup replacing the 4510 with an 3750-e for testing which stays stable. So i need help with the 4510
Setup mpls---g0/0/1---4451- g0/0/3 ---- g1/1 ---- 4510-r-e

as you can see above i have placed commands into g1/1 trying to disable ip device tracking in case this is the culprit. I havent had it running long enough for the links to go downto see with this addition.
interface Vlan11

ip address 10.150.11.1 255.255.255.0
all is well for a few hours then all comunication stops between g0/0/3 and g1/1
I have even removed all eigrp and vrrp statements, shut and no shut the interface afterwords but still no ping once it happens. I have to reload a supervisor to get pings back.
the only difference between my 3750-e which works and this 4510r-e is this new ip device-tracking
anyone think it has to do with g0/0/3 having vrrp on it with a virtual mac address as well as the interface mac connected to g1/1 which has ip device tracking enabled ?
