We are adding 3 mpls sites that will terminate into a 3750 but cannot rurn EIGRP. This 3750 also terminates other Metro LAN offices as well that run EIGRP. Am I better off running OSPF and redistributing between EIGRP or running static routes for the MPLS?

Thanks in advance.

Personally for 3 sites i would use statics and simply redistribute those statics into EIGRP. Easier to configure and a less overhead on the switch not having to run another dynamic routing protocol.

Edit - the above assumes you don't have a huge amount of statics per site, hopefully you can summarise each site ?

Jon,

Thanks for the advice. Another question for you about the 3750. The provider gave me a CE ip, so I would just create a layer 3 interface for that ip and create a vlan interface for our Internal subnet? I get confused on the 3750.

Thanks

Yes. On the port that connect to the provider -

int gi1/0/1

no switchport

ip address x.x.x.x

and then for your internal vlans you just have L3 vlan interfaces eg.

int vlan 10

ip address 192.168.5.1 255.255.255.0

etc. for each vlan.
