Notes From Work
Got involved in a good Frame Relay case study last night and today. Involved Cisco routers and Juniper routers. Customer had to change frame relay type to IETF to get L2TP tunnels to work.

Worked BGP order inbox again today.
ebgp multihop
loopback IP address
GigabitEthernet interface cards
2 x T1 3 Mb multihomed loopback circuit
Nothing like real world, real time, real life lab work. That's called experience. When you apply for a job they want to know your education and your experience. In the Cisco certification world, the only education they care about is CCNA or no CCNA.
After they hear about your education then they want to know about experience.
How many applicants can put down real world, real time, real life CLI experience?
Well, mostly all of them once you get past the entry level positions.
But hardly any of them at the entry level positions.
So I think that would put me ahead of the crowd when I go to put in for the Network Engineer I position in Reston, Virginia.
I figure I'll start putting in for jobs in Reston beginning in January of 2009. I'm not an any big hurry to leave Atlanta right now.

Regarding: DS3 circuit install.
account team calling in with customer, mns, and cpe attempting to bring up circuit.......router could not see hard loop from cpe at customer premise demarc.....bridged qwest........qwest found missing xc......routers now up/up but dropping packets when ping customer ip......sprint side router clean to soft loop at tellabs 6500 bbdcs but dirty to closest soft loop from qwest on time slot 5 of oc48 handoff......this is first circuit to be turned up on this oc48.....i am on the line with tsa investigating at this time........i also have called qwest maintenance and opened telco ticket on oc48 taking errors call before testing.....doug kenline

Job Title: NETWORK OPS TECH II
Job Description: Focuses on the overall operations of the network, including network performance, installation, and/or maintenance. Conducts routine network operations activities, including translations and other duties involved with the preparation needed prior to installation or the tracking and analysis of network elements.
Expert or technical non-exempt role. Serves as a subject matter expert in service, production, or support area of responsibility. May serve in a lead capacity.
The Network Ops Tech II will perform physical layer implementations of all domestic customer terminating broadband transport services to encompass Digital Signal Three (DS-3) and Optical Carrier (OC-n) levels supporting Sprint's IP, ATM, Private Line, and Frame Relay product inventories. The Network Ops Tech II requires thorough knowledge of Sprint's Network Provisioning practices, as well as Sprint's SONET architecture and various terminating elements to include wideband and broadband DCS, add drop multiplexers, routers, ATM and Frame switches. Requires disciplined time management, ability to work independently (with little or no direct supervision) and solid communications skills. Previous performance / attendance will be considered.

Notes From Work
Cisco 12000 router OC3 POS interface would come up/up (looped) with 100% good ping to its own internal diagnostic loopback, however, router would not come up/up (looped) and could not ping STS3C software loopback at Sycamore 16000 on other side of fiber crossconnect in same switch site.
The odd thing was that a show controller report was reflecting back that router's information telling us that the router was in fact seeing the software loopback in the Sycamore 16000 proving the fiber crossconnect good. Why would it not come up/up (looped) and ping?
I tore down the crossconnects in the Sycamore and reconfigured the Sycamore port as an OC12 then reconfigured it back again to OC3. I then rebuilt the STS3C crossconnects in the Sycamore and the router is now testing good to the software loopback in the Sycamore. Up/up (looped) with 100% good ping !!!!!!!!!!!!!!!!!.

Notes From Work
I joined a conference bridge with the customer for a hotcut of FastEthernet service. Customer needed to move from old Cisco router to new Cisco router on Sprint side to support Class of Service for customer VOIP application.
Involved at the Sprint switch site was a Transition Networks CBFTF-1014-100 media converter. After swinging the fiber crossconnect to the new Sprint router the FastEthernet port came up/up with good ping to Sprint side IP address, however, it was dropping packets to customer side IP address.
Sprint changed to half-duplex and problem cleared even though customer router remains on full duplex. Customer circuit is up and passing traffic on new router at this time.
