INE Vol 1 - Multicast Lab 1 - ip pim dense mode.

I still have to revisit the last lab and review the comments in the last post but I went ahead and did the first lab of the IP Multicast section in Vol 1 INE.

Relatively easy as it's basic PIM Dense mode multicast and was covered under R&S.

There's 13 labs in this section and that will complete Vol 1. I'm also going over the CoD for SP from INE too and I'm finding them very helpful

I'm thinking of going on to IEMENTOR's lab book... but after that, what should I tackle next? IPX vol 2 or INE vol 2 (both have 10 labs)...

INE Vol 1 - Lab 26 - finished - Mulicast over MPLS VPNs

I completed this lab, albeit, I had to cheat and look at the solutions for some parts since I wasn't sure what to do.

Question:

1. What is the purpose of MDT under the VRF?

I suppose, I'll Cisco Univercd or google it.

Also my verifications didn't come up. When I do a "show ip pim vrf SW1-SW2 neighbor" I don't actually see the tunnel0 interface of R3 or R6. The tunnel interface is up/up though.

Think I have to read about Multicast over MPLS A LOT more.

INE Vol 1 - Lab 25 - finished - MPLS QOS

QoS is pretty straight forward for SP as it is for R&S. Just have to read carefully what's being classified, what's being marked, and where and what direction to apply the service policy. Then you have to make sure it's consistent throughout the SP network.

It's more of exercise in being careful and thorough then anything else.

On to the Last lab in the MPLS section...

INE Vol 1 - Lab 24 - finished - TE Unequal Cost Load Balancing

Completed this lab pretty easily since it was combination of the 2 before it, one dynamic tunnel and one explicit tunnel, manipulating the tunnel bandwidth for unequal cost load balancing via OSPF.

Something I don't understand is why INE didn't have TE labs based on ISIS, the 3 TE labs were using OSPF. I understand they are pretty similar to each other with an addition of using Wide Metric (metric style wide) under the physical interfaces. But still, it would have been nice to through 1 lab in there with IS-IS.

On to the next lab.

INE Vol 1 - Lab 23 - finished - TE Explicit PE to PE tunnel.

Very similar with the last lab with exception of creating an
'ip explicit-path name ABC enable' and then on the tunnel interface
'tunnel mpls traffic-eng path-option 1 explicit name ABC'

One gotcha is to make sure that the HOPs in the list are correct... I had a 10.x.x.x network but I put it in as 150.x.x.x because the rest of the network was like that.

Another good one to review and dissect.

INE Vol 1 - Lab 22 - finished - TE Dynamic PE to PE tunnels

This one was my first exposure to Traffic Engineering (TE) and it was an eye opening lab on how much I don't know about TE.

Notes:
1. enable 'mpls traffic-eng' globally on MPLS routers (PE and P)
2. enable 'mpls traffic-eng' on a per interface basis for the links that are MPLS enabled
3. enable 'mpls traffic-eng' under the OSPF process specifying a router-id and area
4. configure RSVP on a per interface basis for the tunnel path
5. configure tunnel interfaces on the PE end points
6. advertise the tunnel interface/ip in OSPF.

TE is something I need to read up on but doing the lab before hand actually will help understand what I'm going to read.

INE Vol 1 - Lab 21 - Question? - Controlling MPLS Label Distribution.

So I configured the following to limit the distribution of labels local to a router.

R3's Loopback is 150.1.3.3/32 and R6's Loopback is 150.1.6.6/32

#access-list 1 permit 150.1.3.3
#access-list 1 permit 150.1.6.6
#access-list 1 deny any

#mpls ldp advertise-labels for 1

But I'm still able to see labels for other prefixes...

Any thoughts on why this is? I even cleared MPLS LDP Nei * but still see labels for other prefixes...
