There is not straightforward answer to this question. You may need to check best practice recommendation for deploying MPLS.
You Configure MPLS either on Physical or subinterface.
Every Lable add 4 bytes of MTU, so if you just have MPLS, it will add additional 4 byte of interface MTU, if you have MPLS TE, it will add another 4 byte, for MPLS L3 VPN, another 4 byte, so you need to consider how many label stack you will be having when packet enter into service provider edge router.
MTU is maximum size of the packet that can be sent over the link without any fragmentation, it doesn;t have to relate with prefixes, default MTU size for ethernet frame is 1500, so if any packet comes above 1500, and if there is no fragmentation it will get dropped.
Configure mpls mtu on interface, u can also confirm mpls mtu value via below show command
show mpls interfaces detail
1530 MTU value should be enough in MPLS network. Generally we
Can you please elaborate more on your last question
on the other hand, i not sure what the requirements for cisco equipment that perform the function of PE or P, that equipment is suitable for these functions and what IOS?
Now, you need to know which router you should choose as PE or P, is all depend on your requirement
1) Identify what are the feature you need to deploy on PE or P router
2) What memory it will be consumed
3) Required Flash
5) High Availability
May be in your LAB 7200 is ok for PE or P router but not on Service Provider network due to scalability issue, there are lots other thing need to consider while deploying any device on Service Provider network.
I would first collect the requirement, and then see what is the best router fits.
BTW, are you looking this for your LAB or for any customer ?
