Hi,
I need help choosing a MPLS Customer Edge Router. I was thinking about the cisco 800 series, but using the feature navigator I could not find out if the ios has mpls capabilities. ¿Which is the smallest and cheapest Cisco Router with MPLS Capabilities?
Thanks in advance,
Daniel Rojas

Hello Drojasug33,
unless you are trying to setup a Carrier supporting Carrier scenario you don't need to run MPLS on the CE router
so the commands
mpls ldp router-id Loopback0 force
mpls label protocol ldp
They Are not needed and they can be skipped
Be also aware that if you are going to run OSPF as PE-CE protocol you need to configure the PE nodes appropriately.
The OSPF process-id has to match on local VRF site and remote VRF siteto see remote site OSPF routes as O IA (inter area) otherwise they will be seen as O E2 or O E1 (external routes)
Also, you are expected to use area 0 with PE router (the so called superbackbone area) in order to be able to use multiple OSPF areas on CE router
Hope to help

Hi Daniel,
I an MPLS environment usually a CE router does not run MPLS. It utilizes static routes or dynamic routing protocols ie BGP with the service provider router (PE). If you need MPLS, you can use small 2800 router.

Thanks a lot for your help. I was thinking about using this config in the CE.
ip cef
mpls ldp router-id Loopback0 force
mpls label protocol ldp
!
interface Loopback0
ip address 10.0.0.9 255.255.255.255
!
interface Ethernet0/0
ip address 34.0.0.1 255.0.0.0
no cdp enable
!
router ospf 1000
log-adjacency-changes
auto-cost reference-bandwidth 1000
redistribute connected subnets
network 34.0.0.0 0.255.255.255 area 1000
network 10.0.0.0 0.0.0.0 area 1000
Are the three first commands necessary?
Thanks again.

Hi Daniel Rojas,
Reza is right CE router only routes IPV4 packets to PE,they do not participate in label switching as PE and P's used to.So you can go with 2800/2900/1800 series at CE end.
Hope to Help !!
