Hello Experts, I am a lot confused about the different types of optics and media types. I will try to list some of my confusions: I think when we say "optics", it means the same thing as transceivers...sfp,sfp+ etc are kind of transceivers, right? Is media type one of: "copper" or "fiber"? If copper is the media type, then what transceivers can be put on each side of the cable? If fiber is the media type, then what optics/transceivers can be put on each side of the cable? Is it necessary to have same types of optics at each end of the cable? can a copper cable be connected to an RJ45 port at one end and to a 1000Base-LX/LH on other end? Or is 1000Base-LX/LH is just for fiber and no copper? I am also confused about what all optics are compatible with each other...for eg, if I want to have some optic at one end, how can I find out what optics are compatible with it and can be used at other end. What is meant by connector and optics? What is LC/SC connector, SR/LR optics... Sorry these are beginner questions and may have been answered already. But I could not find any single doc which could have explained things clearly. So any help is appreciated.

I read http://blog.ipexpert.com/2010/11/08/bgp-peering-and-default-routes/ and understood that BGP speaker will not initiate BGP connection with the other BGP router if it can reach it via default route only...And BGP peering will not come up at all if both the BGP speakers know each other via default routes only....I could not understand the reason behind this though...Could any expert help me in understanding the underlying reasoning?

That makes sense, but I am still confused. I was reading article http://blog.ipexpert.com/2009/09/16/mpls-l3-vpn/ where the author has used both global as well as interface level commands. Interface level would not have been needed at all if global command is used, right?

That's what my question was about, why do we need "mpls ip" global command at all (when we anyways have to enable mpls on interface level separately)...What is the point of global command?

What is the purpose of "mpls ip" global command? I think just enabling mpls on an interface by using "mpls ip" should be sufficient, but then what is the purpose of the global level command?

I read that if next-hop of a route in VRF is known via global routing table, then it is normal and connection will work..Why is it so? Shouldn't the next-hop also be known in same VRF? Please suggest.

I know OSPF virtual-links can connect non-contiguous backbone areas. Can virtual-links also connect two non-backbone areas? For example, if we have area2---area0--area2, can virtual link connect the two areas with same ID 2 here? If this is possible, then how will the config be?

I am confused about the use case of bgp inject-maps. If the goal is to inject specific prefixes, then why not just add an ip route <network> <next-hop> statement for more specific prefix (so that the specific prefix appears in routing table) and then add a network statement under router bgp so that the specific prefix appears in bgp table also? Could any expert help? I was reading about the feature at https://blog.initialdraft.com/archives/3527/

Thanks Cadet. But why will anybody want to use this command when normal BGP config works just fine? I guess there is no need, just that if IPv6 (or protocol other than IPv4) is used, then this command is a must as IPv4 is default for BGP...Is that right?

I recently saw the command "neighbor x.x.x.x activate" under router bgp configuration. Neighbors are automatically activated if configured properly. Then why do we need this command?
