Great configuration. Working in ISP?

mzulk said...

Thanks. Yup, I'm working with ISP. Any details you need, you may email mail at mzulk@yahoo.com

adios

mahertac said...

Yes. Me too working at ISP. Almost 2 years of designing, implementing, troubleshooting MPLS VPN. Great to hear that you're doing the configuration. Can reach me mahertac@gmail.com

See ya!

mzulk said...

Welcome welcome

I'm with ISP for almost 10 years, mainly focus in performing POC for various of technologies.

Hopefully, we may share our experiences.

adios

mahertac said...

Thanks for the welcoming. I do appreciate. Mostly on my deployment, we do manually on troubleshooting except for the provisioning I'm using VPNSC - nothing much can be done via that software. Cisco mention to migrate to use ISC.

Sometimes during the hard days become complicated to troubleshoot. Have you ever tried to use ISC?

buzzinhornets said...

Yeah, can share-share our experience... :-)

mzulk said...

Hi

I hate using either VPNSC or ISC, because Cisco is not good in these areas, I think.
However, we are using ISC hehehehe plus normal command line for customer provisioning. Looks like ISC is not matured yet.
I prefer to use command line, and easy for troubleshooting.

adios

mahertac said...

Yes. I absolutely agreeeeee 100%. Manually being done but for the management, it become tedius to manage and control...for managing route-target, should be okay...hahahahaha...

mzulk said...

Hi buzzinhornets

Come and join us hehehe

mahertac said...

Hi mzulk,

Have you ever tried to setup or configure MPLS QoS DiffServ in PE routers? I'm trying to use DSCP/IP Precedence but seems not to be promissing. Suck doug! :)

mahertac

mzulk said...

Hi Mahertac

Nop. Not yet. Might test and needed in future.

Our IPVPN is quite new. Before this, we are the Frame Relay provider. So, we are in the phase of getting POC on IPVPN.

adios

mahertac said...

Hi mzulk.

Yeap. From the configuration I see that you're on FR technologies. Mine, we a using full blast of pure IP networks :) FR makes me headache :) Even nowdays as well, especially Cisco.com still promoting using FR on example on WAN technologies.

Anyway, glad to hear that.

mahertac

mzulk said...

Hi Mahertac

Hehehe we r expert in FR rather than IPVPN. Most of our customers running FR since 1997. We are happy with FR, but we are using Nortel switches as FR nodes, not Cisco hehheeh. Cisco used just for CPE.

adios

Can anyone recommend the top performing Remote Management program for a small IT service company like mine? Does anyone use Kaseya.com or GFI.com? How do they compare to these guys I found recently: [url=http://www.n-able.com] N-able N-central remote pc software
[/url] ? What is your best take in cost vs performance among those three? I need a good advice please... Thanks in advance!
