Blocking private AS
by Thomas Magill 27 Nov '13

27 Nov '13

I am thinking about implementing a filter to block all traffic with private AS numbers in the path. I see quite a few in my table though so I am concerned I might block some legitimate traffic. In some cases, these are just prefixes with the private appended to the end but a few have the private as a transit. Is this a good idea or would I likely be blocking too much legitimate traffic? The filter I am using currently shows the following: BGP table version is 5462394, local router ID is 209.112.253.4 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path * i58.68.109.0/24 x.x.x.x 0 100 0 6130 9498 10201 65534 i *> y.y.y.y 0 6130 9498 10201 65534 i * i68.115.224.0/24 x.x.x.x 0 100 0 6130 19151 20115 65011 i *> y.y.y.y 0 6130 19151 20115 65011 i * 85.112.22.0/24 y.y.y.y 0 6130 6939 23148 64532 64532 64532 64532 64532 64532 64532 64532 64532 i *> 93.189.194.0/24 y.y.y.y 0 6130 3549 39386 39386 39386 25233 65000 47146 i * i x.x.x.x 0 100 0 6130 3549 39386 39386 39386 25233 65000 47146 i *> 96.60.243.0/24 y.y.y.y 0 6130 2828 4181 65528 i * i x.x.x.x 0 100 0 6130 2828 4181 65528 i * i96.61.232.0/24 x.x.x.x 0 100 0 6130 2828 4181 65527 i *> y.y.y.y 0 6130 2828 4181 65527 i * i96.61.233.0/24 x.x.x.x 0 100 0 6130 2828 4181 65527 i *> y.y.y.y 0 6130 2828 4181 65527 i * i96.61.234.0/24 x.x.x.x 0 100 0 6130 2828 4181 65527 i *> y.y.y.y 0 6130 2828 4181 65527 i *> 148.207.2.0/24 y.y.y.y 0 6130 2828 3257 16531 13579 65090 i * i x.x.x.x 0 100 0 6130 2828 3257 16531 13579 65090 i *> 148.207.40.0/24 y.y.y.y 0 6130 2828 3257 16531 13579 65090 i * i x.x.x.x 0 100 0 6130 2828 3257 16531 13579 65090 i *> 148.207.97.0/24 y.y.y.y 0 6130 2828 3257 16531 13579 65090 i * i x.x.x.x 0 100 0 6130 2828 3257 16531 13579 65090 i * 170.34.100.0/24 y.y.y.y 0 6130 19151 20115 65011 ? * 170.34.104.0/24 y.y.y.y 0 6130 19151 20115 65011 ? * 170.34.113.0/24 y.y.y.y 0 6130 19151 20115 65011 ? * i174.35.1.0/24 x.x.x.x 0 100 0 6130 16467 64565 i * i174.47.199.0/24 x.x.x.x 0 100 0 6130 2828 4323 15065 65123 i *> y.y.y.y 0 6130 2828 4323 15065 65123 i * i192.109.61.0 x.x.x.x 0 100 0 6130 19151 20115 65011 i *> y.y.y.y 0 6130 19151 20115 65011 i *> 196.216.249.0 y.y.y.y 0 6130 2828 3257 8513 8513 8513 36881 65000 36896 37062 i * i x.x.x.x 0 100 0 6130 2828 3257 8513 8513 8513 36881 65000 36896 37062 i Network Next Hop Metric LocPrf Weight Path *> 209.172.69.128/30 y.y.y.y 0 6130 16467 64565 i * i x.x.x.x 0 100 0 6130 16467 64565 i *> 213.146.161.0 y.y.y.y 0 6130 2828 174 64679 48493 i * i x.x.x.x 0 100 0 6130 2828 174 64679 48493 i Thomas Magill Network Engineer Office: (858) 909-3777 Cell: (858) 869-9685 mailto:tmagill@providecommerce.com <mailto:tmagill@providecommerce.com> provide-commerce 4840 Eastgate Mall San Diego, CA 92121 ProFlowers <http://www.proflowers.com/> | redENVELOPE <http://www.redenvelope.com/> | Cherry Moon Farms <http://www.cherrymoonfarms.com/> | Shari's Berries <http://www.berries.com/>

Network topology
by Colin Alston 15 Nov '13

15 Nov '13

Hi all I'm considering trying to come up with some means to automatically detect a networks topology and draw pretty pictures. This is somewhat boring though if a network isn't well arranged with VLANs and q-tag trunk routers and so on (It will just look like a big cloud of junk connected off an assumed switch). Is there any kind of cunning trick to detect standard layer2 switches along a path without stuff like STP?

Inventory and workflow management systems

What software solution do people use for inventory management for things like riser/conduit drawdown, fiber inventory, physical topology store, CLR/DLR, x-connect, contracts, port inventory, etc. Any experiences in integrating workflow into those packages for work orders, modeling, drawdown levels, etc. /vijay

We started keeping track of whois databases from March 20th this year, and our earliest data shows it belongs to a Russian company called DIMEDIA LLC.

Route Optimization Software / Appliance
by Babak Pasdar 01 Feb '12

01 Feb '12

Hello Group, I was wondering if anyone could share their experience with any route optimization approaches, methodologies or platforms, either open source or commercial (Internap FCP), that can actively adjust BGP parameters based on latency and number of layer 3 hops to a network rather than AS hops. We have upstreams all over the country and we would like to automate optimization to take the best egress path. Thank you for your feedback in advance.

Looking for a Tier 1 ISP Mentor for career advice.
by Tyler Haske 05 Jan '12

05 Jan '12

Hi. I have some big goals and a lot of enthusiasm but I need direction. I'm looking for a mentor who can help me focus my career so eventually I wind up working at one of the Tier I ISPs as a senior tech. I want to handle the big pipes that hold everyone's data. This is what I want to do with my life. I have my CCNA, and when I graduate college I'll have a CCNP, and the ability to move anywhere in the USA. Please message me off-list. Thank you, Tyler.
