Two domains, two dhcp servers (help with subnet)
Simple problem there my friend – both domains are currently on the same subnet (Network Range). The 255.0.0.0 (/8) you mentioned can be “subnetted” to smaller chunks that will solve the issue you’re having. From what you’ve posted, a good option is to change your subnet mask to a /24 (255.255.255.0): Domain 1 = 10.128.101.x [...]

Speed benifits of MPLS and reasons
Multi-Protocol Label Switching (MPLS) is really beneficial for ISPs to quickly forward traffic based on 1 to 3 labels inserted in the packet header (between the L2 and L3 info). It differs from “regular” ISP connections in that it doesnt need to read the L3 (IP) addresses to forward your traffic. PLUS, the MPLS tagging [...]

With both wired and wireless network connection, prefer to go wired, but metric doesn’t always work.
When adding a second connection (i.e. a wireless connnected system adding a wired LAN connect) the client system should determine costing of both routes to the destination over each NIC to determine which NIC to send traffic out. This is all based off of the TOTAL routing costs of each route to the destination and [...]

RIPv2, and with IPv6 – RIPng, are used in smaller networks that dont need, or want, the complexity of either EIGRP or OSPF. RIP is easier to configure, administer and edit if needed – no need for wild-card masks or areas or an “AS” – just enable RIP, toss in a few network statements and [...]
