I've been promoting simplicity in IP networks since 1997. In my role as principal consultant at Brooks Consulting, I help clients design and operate large-scale wireline and wireless networks. My specializations include the LTE packet core, IPv6, and cloud to data center network integration.

comment Ubuntu 14.04 dropping ipv6 route and ifstate
Router advertisement. It's a fundamental component of neighbor discovery (roughly the IPv6 equivalent of ARP but with more functionality).

comment How to have JunOS to learn IPv6 default route from RA?
I don't think this is possible in Junos. Perhaps on MX/BRAS but not elsewhere. I can't find any any documentation to back this up, however.

comment Windows 7 laptop with two active network connections will not perform DNS AAAA lookup under certain conditions
Michael -I changed the network topology in my house to avoid this situation. Regarding your request for broken configuration, I don't know what I could have included. Windows 7 wasn't sending AAAA queries in Scenario 1 in my question. The problem appeared to be an OS problem for multihomed Win7 hosts.

comment JunOS Regular Expressions for AS Path
For the OP's edification, I'll point out that JUNOS regexes differ from Unix regexes in signficant ways such as the basic unit of matching is an AS rather than a character.

comment JunOS Regular Expressions for AS Path
Need clarification. Must exactly two ASes follow 9121? Or do you want 9121 followed by zero or more ASes? Please be specific.

comment MPLS label prefixes
Bruce, the Tier 1 ISPs in the world have built massive MPLS networks without doing what you are suggesting. The ASICs in routers can do label lookups very quickly. You will not realize any gains here. In addition, router memory is a miniscule component of the cost. You don't need to optimize here. This seems more like an intellectual exercise for you rather than an attempt to solve a problem that you are facing in a real-life network.

Bruce, I suggest editing your question to describe what you want to accomplish.

comment IPv6 configuration for my private network when prefix delegation is not supported by the provider?
Yes, a /48 or /56 would be ideal. We still have work to do in convincing some engineers that the scarcity approach to IPv4 addresses is not applicable to IPv6.

comment IPv4 as default IP in dual stack
IPv6 should be disable as a last resort. We are in the midst of a transition to IPv6. If you find issues such as higher latency with IPv6, talk to your provider. The ISP may have incongruent IPv4 and IPv6 peering topologies. The engineers may not understand the ramifications to the user experience. We need more users using IPv6 in order to pressure infrastructure and content companies to fix problems. Most users will not be as technical as the OP and won't realize that turning off the IPv6 is an option...for now.

comment How can I make my web server reachable via IPv6 on the AWS platform?
Interesting. I wasn't aware that Cloudflare had an automatic IPv6 gateway. Thanks for the tip, Marcus.
