Re: Failover how much complexity will it add?
by adel＠baklawasecrets.com 13 Nov '09

Actually thinking about this, I still need to understand the implications of not taking a full routing table to my setup. So what is the likely impact going to be if I take partial instead of full routing table. Would appreciate any feedback on this. My organisation is only looking at using BGP as a means of failover between two separate upstream ISPs. We are not an ISP.

Resilience - How many BGP providers
by adel＠baklawasecrets.com 12 Nov '09

12 Nov '09

Hi, After recent discussions on the list, I've been thinking about the affects of multiple BGP feeds to the overall resilience of Internet connectivity for my organisation. So originally when I looked at the design proposals, there was a provision in there for four connections with the same Internet provider. Thinking about it and with the valuable input of members on this list, it was obvious that multiple connections from the same provider defeated the aim of providing resilience. So having come to the decision to use two providers and BGP peer with both, I'm wondering how much more resilience I would get by peering with more than two providers. So will it significantly increase my resilience by peering with three providers for example, as both of the upstreams I choose will be multihomed to other providers. Especially as I am only looking at peering out of the UK. Hope the above makes sense. Adel

qos 3560
by Bogdan 12 Nov '09

12 Nov '09

hello i am playing with qos on some devices - cisco 3560 - cisco 7609 and i have some things that i don't seem to understand. 1. in 3560, i enable mls qos, on the ingress port applyed policy map, classify the packets with acl, mark, all good. on the egress ports i use srr-queue with shape/share, everything is fine, it is working. http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/… 2. reset to defaults the 3560 in 7606 i pick up a vlan, and apply a policy-map and set dscp 40 on egress of that vlan 3560 in uplinked in 7609 in 3560 i can see the "marked" packets, and i have matches on the dscp set earlier (sh mls qos int xx stat). the problem is: when i apply the srr-queue in 3560 on egress (towards the test port), it does not work. if i enable mls qos on 3560, i cannot match anymore the dscp 40 from the 7609 is it normal? do i have to apply the qos stuff (point1) on all switches i want qos on? i mean, i cannot set dscp in one "core" device and use that in the whole network ? thanks

Minimum IPv6 size

Since we're on the topic of what's commonly accepted in IPv4 land (a /24), what's the story in IPv6 land? It seems to me that a /32 is a fur sure thing, but others will accept down to a /48, too. ~Seth

Spyware and Antivirus detection increase
by Elijah Savage 12 Nov '09

12 Nov '09

All, This may not be the right audience but I do not know of a better set of experts to ask this question. We monitor antivirus and spyware activity very close on our desktop and laptop environment. Often you can correlate this activity with an increase in bandwidth. The bandwidth is not an issue but this month we see a very big spike in antivirus and spyware detection compared to last month, 12,000 detections last month compared to 38,000 so far this month. We have all the data and know what signatures are being tripped and a good idea of where they are coming from. The question I have is this, is anyone else seeing an increase and have any idea why? Is it just the time of the year with it being the holiday season?

Performance to and from Japan (who to connect to?)
by Operations 12 Nov '09

12 Nov '09

Greetings, Im sure someone here is GREAT with connecting to Japan so I ask the following: We have a POP in 600 West 7th street, Los Angeles. What provider can I cross-connect to there to get better performance to Japan? Are there Japanese providers on net in that building? Anyone want to peer with me there that can give me better routing to Japan? Thank you very much Nanog. NJ Critical Data Network http://www.critical.net

Re: Gig Throughput on IPSEC
by adel＠baklawasecrets.com 12 Nov '09

12 Nov '09

On second thoughts, thinking about this I am probably looking for some kind of Layer2 encryption devices. This will make things a lot easier for the deployment. Any experiences, thoughts on these types of devices, would be much appreciated. Adel On Wed 9:25 AM , adel(a)baklawasecrets.com sent: Hi, I have a requirement to encrypt data using IPSEC over a p-t-p gig fibre link. In the past I've normally used Juniper to terminate VPNs, as I have found them excellent devices and the route based VPN functionality very useful. However looking at their range, only the ISG will do a gig of IPSEC. I'm leaning towards keeping my exising Juniper SSG550's for firewall/routing capability at each site. Then having a separate encryption devices to handle the site-to-site vpn requiring the gig throughput. Does anyone have any suggestions on devices to use? Adel
