Carrier assistance
Could anyone from Qwest/CenturyLink, TW Telecom, or XO with the ability to assist with some null routing please drop me a line off-list? Got a customer getting attacked in one of my sites and our calls are languishing in hold queues. Thanks in advance, - Darrell
Feedback on Entrasys Switching
Was hoping that anyone with experience with the Entrasys K or S series switches would be willing to offer any feedback on the platform, organization, support, software, etc. Interested in fairly vanilla L2 and L3 functionality and performance at high 1 and 10G interface density. Considering an evaluation and would value some informed argument for or against. Happy to take replies offline. Will be glad to summarize for anyone interested. Thanks! - Darrell
Re: Commerical Backup Solutions
Recently finished developing a product around Commvault Simpana. Fairly happy with their API and reporting capabilities. Application specific plugins (MySQL, mssql, exchange, etc) are pretty solid so far as well.

Null routing the source isn't going to stop the inbound packets from reaching the target of the attack. All that's going to do is blackhole packets back to the attacker from anyone hopping through the router carrying the null route. - Darrell

[NANOG] Comcast (AS 7922 -> 33491) issues?
I'm seeing tons of availability issues to networks with AS paths ending in "7922 33491". A couple of the prefixes in question are 98.214.0.0/15, 69.137.240.0/20, 73.117.0.0/16, and 67.175.0.0/16. I spoke with Abovenet earlier this morning - they say its due to L3 suppressing those announcements to some of their peers. Initially I thought they were just making things up, until I started seeing "% Network not in table" responses to BGP lookups on the router where I peer with Sprint: #show ip bgp 98.214.184.18 % Network not in table #show ip bgp 69.137.251.134 % Network not in table And yet... #show ip bgp 98.214.184.18 BGP routing table entry for 98.214.0.0/15, version 26493985 Paths: (2 available, best #1, table Default-IP-Routing-Table) Advertised to update-groups: 3 4 3491 7922 33491 63.218.31.1 from 63.218.31.1 (63.218.30.9) Origin IGP, localpref 100, valid, external, best Community: 228787176 228787177 228794098 6395 3356 7922 33491 216.140.65.73 from 216.140.65.73 (216.140.9.56) Origin IGP, metric 160, localpref 100, valid, external #show ip bgp 69.137.251.134 BGP routing table entry for 69.137.240.0/20, version 26493909 Paths: (2 available, best #1, table Default-IP-Routing-Table) Advertised to update-groups: 3 4 3491 7922 33491 63.218.31.1 from 63.218.31.1 (63.218.30.9) Origin IGP, localpref 100, valid, external, best Community: 228787176 228787177 228794098 6395 3356 7922 33491 216.140.65.73 from 216.140.65.73 (216.140.9.56) Origin IGP, metric 160, localpref 100, valid, external Based on what I'm seeing, someone out there has to be seeing similar behavior.
