We have 5 working 7206VXRs+NPE-G1, but this is only one using 1000BaseTX
connectivity to the switch (rest routers are connected via SX and LX
optics). And only here we have 1000BaseTX and this kind of problem...

Above commands will be omitted due they are defaults on Catalyst
switches. eg.

labsw1(config)#int giga0/17
labsw1(config-if)# switchport trunk encapsulation dot1q
labsw1(config-if)# switchport mode trunk
labsw1(config-if)#switchport trunk native vlan 1
labsw1(config-if)#switchport trunk allowed vlan add 1
labsw1(config-if)#^Z
labsw1#sh run int giga0/17
Building configuration...

Current configuration : 141 bytes
!
interface GigabitEthernet0/17
 switchport trunk encapsulation dot1q
 switchport mode trunk
 load-interval 30
 no cdp enable
end

No this time, this is L3 switch, and we're using OSPF here. Year VLAN
using SVI from this problematic 7200...

I didn't try - this is working router with about ~200M of customers
traffic. If I didn't find any good workaround for my problem we'll
make maintenance window and will do couple of tests.
