Mikrotik 发布首个RouterOS v7 LongTerm 版
Bugtik 自己认为 ROSv7 总算可以用了 .经日常测试 , V7.20.6 之后的新版本的确没什么问题 .
除了 MPLS VRF MLAG...这种日常生活中不太会用功能没有测 . OSPF 和 BGP 现在试下来都可以用了 .
RouterOS v7 与 v6 BGP 的逻辑不同 . v6 Filter 把不要的 IP过滤掉 , 他就直接"拒之门外"了 , 路由表里找不到了 . v7 的话 , 如果上游发的是全表 , 那整个全表都会被收下来 , 被丢弃的路由也会在路由表里找到 .
优缺点明显 . v6 占用系统资源很少 , 但是调整filter之后需要再问上游重新去把之前丢弃的路由给收回来 . v7 占用系统资源多 , 全表都在本地 , filter调整后路由即刻就产生了变化 .
直到 v7.17之后 , 更新BGP filter 后路由表崩溃 , 使用系统资源过大导致影响正常网络数据转发速度的问题才逐步得到解决 .
以下观点仅代表个人意见 :
除非由于硬件驱动问题必须使用 RouterOS v7 才能被驱动起来 , 或者说ARM的硬路由出厂就已经是 v7 . 只要日常要用到 BGP的话 , 还是要考虑用v6版 , 权衡两者的利弊之后再上v7版 .

What's new in 7.20.7 (2026-Jan-08 11:40):
*) bgp - fixed l2vpn-cisco decoding (introduced in v7.20);
*) bgp - fixed occasional corruption of MPLS labels in BGP VPN update messages;
*) bridge - fixed dynamic switch-cpu VLAN creation (introduced in v7.20);
*) bridge - improved system stability when forwarding traffic with fast-path and bridged interface gets removed or disabled (introduced in v7.20);
*) bth - make user private-key sensitive;
*) console - fixed empty output in route menus when using "print where gateway";
*) console - updated copyright notice;
*) firewall - clear relevant masqueraded connection tracking entries on IP address change;
*) ipv6 - initialize RA receiving when enabled and without any other IPv6 configuration;
*) log - fixed memory leak;
*) lte - fixed LTE interface IPv6 address generation to use EUI-64 (introduced in v7.20);
*) lte - fixed no re-connection after cellular network requested APN deactivation on Chateau 5G ax R17;
*) ovpn - fixed OVPN server handling on reboot (introduced in v7.20);
*) ovpn - improved system stability when using cipher=blowfish128;
*) sfp - fixed "sfp-tx-fault" state indication for CRS520-4XS-16XQ;
*) sfp - fixed missing link up/down notifies;
*) switch - fixed non-IP multicast packet receive on 98DX8208, 98DX8216, 98DX8212, 98DX8332, 98DX3257, 98DX4310, 98DX8525, 98DX3255, 98CX8410 switches;
*) system - detect policy mismatch sooner if script is executed internally by some other service;
*) ups - fixed board hibernation shutdown;
*) wifi-mediatek - added Superchannel regulatory profile;
