I was trying to configure VRRP on the two routers. and then I gave up and deleted all the vlans. But these error messages indicate that i did not have cleaner cleanup.
Message on Router1 :
CDP-4-NATIVE_VLAN_MISMATCH: Native vlan mismatch discovered on gigabitethernet 2/11 (11), with Router2 Gigabitethernet2/10 (10)
I see a similar message on Router2:
CDP-4-NATIVE_VLAN_MISMATCH: Native vlan mismatch discovered on gigabitethernet 2/11 (11), with Router1 Gigabitethernet2/10 (10)
Any Idea ?

what vlans are set on each interface?
Arvin,
What type of "routers" do you have? Is it Layer3 switches or physical routers? What model? If they are physical routers, how they interconnected, directly with a crossover cable, or through the switch or hub? How switch ports are configured? Configured as a trunk or as an access-port, and what VLANs?
How your router interfaces configured? If you don't use VLANs on the router, you should remove sub-interfaces, remove trunking, and move an IP configuration to a physical interface.
If you still have a question, would you post the following portions of the config: (1) Router1 & Router2 Gigabit interfaces (and corresponding sub-interfaces). (2) If you have a switch between them, then configuration of both ports.
Good luck,

Hello snipped-for-privacy@gmail.com,
Do you do trunking/tagging on these ports?
