TE quiz, here we go !

Q1.
Name the advanteges of MPLS traffic engineering

Q2.
What are the components of MPLS traffic enginnering?

Q3.
What are the attributes of the links enablefor traffic enginnering?

Q4.
Name the 6 ways how you can forward ip traffic onto a TE tunnel

Q5.
Name 4 kind of path options you can specify

Q6.
When you have an MPLS VPN network and TE tunnels that do not always have the PE routers as head/tail end routers, what do you need to have?

Q7.
What is the LSR that is the head end router of a backup tunnel called?

Q8.
Why do you need a link-state routing protocol for MPLS TE?

Q9.
What is the feature called that has the IGP advertise TE tunnels as links?

Q10.
How does the head end LSR of a TE tunnel knows that the tunnel is fast rerouted over a backup tunnel?

------------------------------------------

A1.
- sttering traffic so that all links in the network are used optimally
- routing traffic around hostspots in the network
- fast rerouting traffic around link and node failures

A2.
- OSPF or IS-IS with TE extensions enalbed
- RSVP
- Link attributes
- TE tunnel attributes

A3.
- maximum reservable bandwidth
- attribute flags
- TE metric

A4.
- static route
- policy-based routing
- forwarding adjacency
- autoroute announce
- direct mapping of AToM traffic onto TE tunnels
- CBTS

A5.
- explicit
- explicit with exclude address
- explicit with loose next address
- dynamic

A6.
- LDP enabled on the links
- LDP targeted session on the TE tunnel if the tail end router is a P router

A7.
the point of local repair(PLR)

A8.
to know the attributes and available bandwidth of all links

A9.
forwarding adjacency

A10.
receiving a PathErr message from the PLR, indicating that local repair is active
