IP OSPF priority command?Router-id 223.255.255.255.Why not 255.255.255.255? Because BGP can only recognize 223.255.255.255, if you set a Router-id greater than 223.255.255.255, BGP and OSPF redistribution will be problematic ( BGP and OSPF must use the same router-id when doing BGP and OSPF redistribution Some of the other redistribution considerations: 1. Redistribution only once on the same router. If you redistribute the RIP into OSPF and then reassign OSPF to

Is-is neighbors cannot establish the following troubleshooting: Network environment The Is-is routing protocol is run between two NE80, and a Ip-trunk interface is connected through the transmission via 3 2.5G POS interface. Ip-trunk link status is up, two NE80 devices can ping each other, but cannot establish is-is neighbor relationship. Fault analysis There may be several reasons for this Is-is configuration is inconsistent on step 12 devices. Step 22 device versions are inco

symmetric encryption, because the ChaCha20-Poly1305 is a AEAD mode, MAC algorithms are not required, so the MAC column is displayed as AEAD. To learn more about CipherSuite, read the long article "TLS protocol analysis and modern encrypted communication protocol design". In short, when configuring CipherSuite, you must refer to the authoritative documentation, such as the recommended configuration of Mozilla and the configuration used by CloudFlare.

Today, I found that the host could not be accessed. I thought there was something wrong with burst. I wrote an email asking why. I accidentally saw an email written by burst in my inbox, the title is that the traffic usage exceeds the standard. I can only use surprise to describe this email, because the traffic of the purchased VPs is 1000 GB/month. How can this problem be solved? What surprised me more, I used veportal to check that the traffic usage was 23424.44 GB. I relied on it for more tha

Talking about JavaScript-based DDOS attacks and javascriptddos CloudFlare protects millions of websites and summarizes the oldest and most common non-DDoS attacks. In traditional DDoS attacks, attackers can control a large number of bots and then send a large number of requests to the target server to prevent legal users from accessing the website. However, in recent years, DDoS attack technologies have been constantly updated: attackers use a new an

significance of the problem. Cloudflare had a significant outage as a result of the leap second. Cloudflare is exactly the kind of company, that should is able to use Go successfully. This meant, the problem is too important to being left unresolved. So fixed the underlying problem, and did so without adding a new API. Explaining gradual code repair Another problem that comes up in large codebases was the

This is an article by Cloudflare Filippo Valsorda, published in Gopher Academy in 2016, although it has been in the past two years, but it still has meaning. Previously crypto/tls too slow and net/http very young, so for Go Web server, it is usually wise of us to put it behind the reverse proxy, such as Nginx, and now do not need. In CloudFlare we recently experimented with direct burst of pure go service a
