Routeros关于动态路由ospf优先级cost和priority的区别和联系插图

动态路由ospf里

cost是用来设置动态路由优先级的,比如R1到R2有两条路可走,cost低的,路由优先走这条路,cost一样的话,就负载均衡,两条路都走;

priority是用来选班长和副班长用的,priority高的优先级就高,更可能选上班长。否则ospf会自动选择DR和BDR。

 router’s priority. Used to determine the designated router in a broadcast network. The router with highest priority value takes precedence.

Priority value 0 means the router is not eligible to become designated or backup designated router at all.

    Hello, my name’s Eric and I just ran across your website at l8cc.com…

    I found it after a quick search, so your SEO’s working out…

    Content looks pretty good…

    One thing’s missing though…

    A QUICK, EASY way to connect with you NOW.

    Because studies show that a web lead like me will only hang out a few seconds – 7 out of 10 disappear almost instantly, Surf Surf Surf… then gone forever.

    I have the solution:

    Talk With Web Visitor is a software widget that’s works on your site, ready to capture any visitor’s Name, Email address and Phone Number. You’ll know immediately they’re interested and you can call them directly to TALK with them – literally while they’re still on the web looking at your site.

    CLICK HERE http://www.talkwithcustomer.com to try out a Live Demo with Talk With Web Visitor now to see exactly how it works and even give it a try… it could be huge for your business.

    Plus, now that you’ve got that phone number, with our new SMS Text With Lead feature, you can automatically start a text (SMS) conversation pronto… which is so powerful, because connecting with someone within the first 5 minutes is 100 times more effective than waiting 30 minutes or more later.

    The new text messaging feature lets you follow up regularly with new offers, content links, even just follow up notes to build a relationship.

    Everything I’ve just described is extremely simple to implement, cost-effective, and profitable.

    CLICK HERE http://www.talkwithcustomer.com to discover what Talk With Web Visitor can do for your business, potentially converting up to 100X more eyeballs into leads today!

    Eric
    PS: Talk With Web Visitor offers a FREE 14 days trial – and it even includes International Long Distance Calling.
