Lab Prep Update

Just finished my 5th day of rack rental sessions in 6 days this evening. I have ebbed and flowed through them. Some of the Labs I have been okay and some, like tonight I got kicked in. I have finally conquered MPLS VPN but am struggling on QoS Traffic Policing, MPLS TE and Multicast Tunnels. For QoS its speed – I know the sequence -> ACL, class-map, policy-map, apply service policy to interface, but I seem to take an age to complete it. The same holds true for MPLS TE. On the Multicast tunneling I just cannot get it to work 100% – even putting in the solutions in some labs does not help!! e.g. IEWB-SP Vol II Lab 1. It turns out there are known issues with multipoint NBMA.

Other issues that have caught me out have included RIP split horizon which took some time to resolve but debug ip rip is a cool tool.

IP: sending v2 update to 224.0.0.9 via Ethernet0/0 (129.1.67.6)
RIP: build update entries – suppressing null update

Rack1R6(config-if)#no ip split-horizon

RIP: received v2 update from 129.1.67.7 on Ethernet0/0
     129.1.7.0/24 via 0.0.0.0 in 1 hops

RIP: sending v2 update to 224.0.0.9 via Ethernet0/0 (129.1.67.6)
RIP: build update entries
        129.1.7.0/24 via 129.1.67.7, metric 2, tag 0
        129.1.67.0/24 via 0.0.0.0, metric 1, tag 0
Rack1R6#sh ip route vrf VPN_A

Routing Table: VPN_A
Codes: C – connected, S – static, R – RIP, M – mobile, B – BGP
       D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area
       N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2
       E1 – OSPF external type 1, E2 – OSPF external type 2
       i – IS-IS, su – IS-IS summary, L1 – IS-IS level-1, L2 – IS-IS level-2
       ia – IS-IS inter area, * – candidate default, U – per-user static route
       o – ODR, P – periodic downloaded static route

Gateway of last resort is not set

     129.1.0.0/24 is subnetted, 2 subnets
R       129.1.7.0 [120/1] via 129.1.67.7, 00:00:08, Ethernet0/0
C       129.1.67.0 is directly connected, Ethernet0/0

Tomorrow is my last rack rental then we’re in the home straight – two days of general studying with notes & lectures, maybe some dynamips between 4 routers just fine-tuning some ideas, confirming notes, etc. I fly to Brussels on Wednesday, Lab on Thursday.
