[f-nsp] NetIron CER 2000 as a metro switch

[Eric Louie]

Ok

 

It’s being used as a base switch.  Each GigE port may be servicing up to 10 customers over a trunked interface, though port bandwidth utilization will rarely exceed 150 Mbps.  Most of those connections will be simple point-to-point IP connections via individual VLANs.  24 ports is the most we’ll need at any site, and the switches are interconnected via backhaul WAN circuits to form a ring or partial mesh as the backhaul topology allows.  IP is routed within the backbone using OSPF.  We have a combination of public (customer assigned) and private (internal use) IP addresses within the backbone.

 

Part of our growth path will be to offer MPLS via VRF circuits between switches, regionally and locally.  Customers with multiple locations in our regional area will have the ability to interconnect their offices using VRFs.  We will also offer IPv6 to our customers as these new switches are installed.  

 

much appreciated,

Eric Louie

Well,

 

First of all, one is a switch who can do a little routing with small RIB capacity while the other is a router who can do a little switching whit high RIB capacity.

 

Again, if you don't state your needs/requirements/sizing, it's going to be difficult to help.

What’s the difference between the CER and the CES?  From the local Systems Engineer, he says “L3 VPNs on the CER, L2 VPNs on the CES”.  Any other notable differences?

 

much appreciated,

Hello Eric,

 

I have been running CER-RT as route reflectors and MPLS PEs for our "small" POPs just fine.

 

Now, if you are looking for metro switchs as a replacement for Cisco ME3600, you should probably take a look at the CES switchs destined for that typical use case.

 

Again, it all depends on your requirements/needs/sizing which you didn't specify.

 

HTH.

I’m considering using the CER 2000 as a mpls PE switch.  I have been told that the CER-RT can also be used as an Internet edge switch (will hold multiple BGP tables)

 

I’m interested in your experiences in configuration and operation in either application.  What are you using for CE devices?  (Brocade doesn’t seem to have a branch office router)

 

(Currently using Cisco ME3600-X for PE and c871 for CE)

 

much appreciated,

Eric Louie
